The Plastic Bending of Beams FortiTestX-46 is a structural mechanics laboratory unit for demonstrating plastic bending theory and collapse load behaviour in mild steel beams. This plastic bending of beams apparatus provides two end supports configurable as simple supports or rigid fixed ends, with a fine screw jack and integral 500 N load cell applying a single point load. Beam deflection is measured using a vernier gauge across both elastic and plastic deformation regions.
Product Overview
The Plastic Bending of Beams FortiTestX-46 enables experimental investigation of beam behaviour beyond the elastic limit, demonstrating the increase in bending moment capacity due to end fixity and redundancy. Two end supports are provided: one is fixed in position and the other allows horizontal travel to accommodate beam deformation during loading. Both supports can be configured as simple supports using knife edges, or as fully fixed ends using clamp plates that restrict end rotation. A fine screw jack mechanism with an integral load cell applies a controlled single point load of up to 500 N to the test beam. Load cell output and vernier gauge deflection readings connect to an external display unit, sold separately. Three fully annealed mild steel test beams are supplied, each 860 mm long with an 8 x 8 mm cross-section. This plastic bending of beams unit demonstrates how additional load capacity is generated as the beam becomes redundant through end fixing, and allows measurement of the collapse load at which a plastic hinge forms. All necessary assembly and operating tools are included. The apparatus must be used with a universal frame and stand, sold separately. Optional LabVIEW-based Software FX-46 enables data logging and results processing on any Windows operating system.
The Reaction of Beam Apparatus FortiTestX-45 is a benchtop structural mechanics unit for experimentally determining support reaction forces in a simply supported beam under various loading conditions. This reaction of beam apparatus uses two spring balances as supports for direct reaction force readout, with six movable load hangers enabling flexible load positioning along a 1000 mm beam. It validates the principle of equilibrium through direct comparison of measured and calculated support reactions.
Product Overview
The Reaction of Beam Apparatus FortiTestX-45 provides a straightforward experimental platform for studying beam support reactions, lever mechanics, and the principle of equilibrium. The apparatus centres on a 1000 mm long steel beam, 7 mm wide and 20 mm high, with 39 holes spaced at 25 mm intervals for precise load hanger positioning. Two spring balances, each with a 10 kg capacity and 50 g least count, act as the beam supports and provide direct readings of vertical reaction forces at each support. Six load hangers can be placed at any hole position along the beam, allowing a wide range of loading configurations including single point loads, multiple point loads, and asymmetric arrangements. The beam weight is 8.12 N and must be accounted for in calculations. By suspending the beam from the free-standing frame and attaching one end with spring balances, the same setup can be used to investigate loads and moments on a lever. This reaction of beam apparatus includes a 1000 mm measuring scale with 1 mm least count for accurate load position measurement. A technical manual is provided for both students and lecturers, covering theory, experiment protocols, and sample results. The full setup mounts on a benchtop frame with all accessories included.
The Buckling of Bars FortiTestX-44 is a structural mechanics laboratory unit for demonstrating and investigating elastic buckling behaviour in bars under compressive loading. This buckling of bars apparatus supports systematic variation of support conditions, cross-sections, materials, and additional shear forces, enabling full experimental verification of Euler’s buckling theory. Force and lateral deflection are measured directly through an integrated force gauge and two dial gauges.
Product Overview
The Buckling of Bars FortiTestX-44 provides a clear and controlled demonstration of elastic buckling in long slender bars subjected to compressive forces along their longitudinal axis. When a critical compressive force is reached, such bars lose stability and deflect laterally without material failure, remaining within the elastic stress zone. The apparatus includes a load mechanism for applying compressive forces to test bars that can be pinned or fixed at both ends depending on the buckling condition under investigation. A force gauge measures the applied compressive force, and a dial gauge records lateral deflection of the bar. Test bars of different materials and cross-sections are supplied: three steel bars (600 x 20 x 4 mm), two aluminium bars (600 x 25 x 6 mm), one aluminium circular bar (600 x 10 mm diameter), and one aluminium bar (600 x 15 x 2 mm). The effect of additional shear forces on buckling behaviour is demonstrated through a separate experiment in which a cable and weight apply a shear force at a joint along the buckling bar. This buckling of bars unit enables calculation of expected buckling forces using Euler’s buckling formula and graphical analysis of deflection against force. All components are organised in a storage system (1170 x 480 x 178 mm) with an approximate total weight of 30 kg. The complete experimental setup is housed in the structures test frame mounting frame.
The Young’s Modulus Apparatus FortiTestX-43 is a wall-mounted experimental unit for investigating the elastic elongation of metal wires under tensile loading. This Young’s modulus apparatus enables determination and verification of the modulus of elasticity for steel, aluminium, brass, and copper wire specimens, with elongation measured by a vernier gauge at 0.02 mm graduation. It covers the relationship between wire elongation, applied load, wire diameter, and material properties within a single compact wall-mounted setup.
Product Overview
The Young’s Modulus Apparatus FortiTestX-43 is fixed to a wall-mounted carrier from which wire specimens are suspended. The bottom ends of the wires are secured using two sliders. A traverse connects the wires at their lower ends and distributes applied load evenly across the specimens. Weights are placed on the traverse to load the wires in direct tension. Wire elongation resulting from the applied tensile force is measured using a moment lever fitted with a vernier gauge, providing a displacement range of 100 mm at 0.02 mm graduation. Wire specimens are available in four materials: steel, aluminium, brass, and copper. Each wire is 1000 mm in length with a diameter ranging from 1 to 2 mm. Experiments investigate elastic elongation as a function of applied load, wire diameter, and material, and enable direct determination and verification of the modulus of elasticity for each material. This Young’s modulus apparatus is suited to undergraduate engineering and materials science laboratory programmes requiring hands-on measurement of fundamental elastic material properties.
The Frame Deflections and Reactions FortiTestX-35 is a structural mechanics laboratory unit for investigating vertical and horizontal reaction forces and sway deflection in portal frames under load. This frame deflections and reactions apparatus includes two aluminium alloy portal frames, one with a uniform cross-section and one with a non-uniform leg, enabling direct comparison of structural behaviour across both configurations. Load cells connected to a Digital Force Display measure support reactions, while a digital deflection indicator records sway at the top of the frame.
Product Overview
The Frame Deflections and Reactions FortiTestX-35 mounts to a test frame and provides a complete experimental platform for studying portal frame behaviour under applied loading. Two rectangular aluminium alloy portal frames are supplied, both nominally 250 mm x 500 mm. One frame has a uniform cross-section throughout, with a 25 mm width and 6 mm breadth. The second frame has a non-uniform section, with one leg reduced to 4 mm breadth, producing a smaller second moment of area on that leg. Students clamp each leg of the portal frame to the test frame supports and apply loads using masses on a hanger at the top of the portal structure. Load cells at the supports connect to a Digital Force Display to measure vertical and horizontal reaction forces. A digital deflection indicator measures sway at the top of the portal frame. Using the measured moments and reactions, students plot bending moment diagrams and compare them against theoretical calculations. Sway direction and its causes are examined and discussed. The experiment is repeated with the second portal frame to compare the effect of the non-uniform section on structural behaviour. This frame deflections and reactions unit is supported by optional LabVIEW-based Software FX-35 for data logging and results processing on any Windows operating system. Virtual experiments within the software simulate hardware testing and extend available test conditions to include larger loads, uniform loads, and different test specimens. An optional Automatic Data Acquisition system enables automated collection and logging of experiment results.
Short Introduction
The Deformation of Frame FortiTestX-42 is a structural mechanics laboratory unit for investigating the deformation behaviour of steel frames under load. This deformation of frame apparatus covers both statically determinate and indeterminate conditions using U-shaped and S-shaped steel frames, with two dial gauges recording deflection at 0.01 mm resolution. It supports application of first-order elasticity theory, the principle of superposition, and the principle of virtual work within a single self-contained setup.
Product Overview
The Deformation of Frame FortiTestX-42 provides a comprehensive experimental platform for studying frame deformation, bending moment characteristics, and support reactions under varied loading conditions. The unit includes two steel frames: a U-shaped frame (600 x 600 mm) representing standard portal construction as found in hall structures, and an S-shaped frame (600 x 600 mm) for demonstrating the applicability of analytical methods to non-standard frame geometries. The U-shaped frame is clamped at one end; the opposite end can be left free for statically determinate analysis or fitted with a roller bearing for statically indeterminate investigation. Two sets of weights with movable hooks apply loads at adjustable positions along the frame. Two dial gauges with a 0 to 20 mm measuring range and 0.01 mm graduation record frame deformations under load. Bending moment characteristics are determined using first-order elasticity theory, the principle of superposition, and the principle of virtual work. The differential equation of the bent line is constructed from these characteristic curves and an integrals chart. Displacements and support forces at the movable bearing are calculated from the bent line and its derivatives. This deformation of frame unit stores all components in an organised storage system within a self-contained experimental frame. Optional frame variants FX-42A, FX-42B, FX-42C, and FX-42D extend the apparatus to portal frames with overhanging ends, redundant square frames, unsymmetrical portals, and square portal frames.
The Heat Exchanger Service Unit ThermoFlux – 7108 is a bench-mounted experimental control unit designed to provide hot and cold water circuits for the investigation and comparison of multiple heat exchanger types under parallel flow and counter flow conditions. This heat exchanger service unit is compatible with up to four interchangeable heat exchanger modules — plate type, concentric tube, shell and tube, and jacketed vessel — enabling systematic study of thermal energy transfer, mean heat transfer coefficients, and temperature curve plotting across different exchanger designs and flow configurations.
Product Overview
The Heat Exchanger Service Unit ThermoFlux – 7108 forms the central control and service element of a modular heat exchanger experimental system. The unit houses a stainless steel hot water tank of 50–60 litre capacity fitted with four electric heating resistances of 1.5 kW each (6 kW total), a PID digital temperature regulator, a K-type thermocouple for water temperature measurement, level switches to prevent dry-running of the heater, a stainless steel cover, and a draining valve. Hot water is circulated through the connected heat exchanger by a 0.75 HP centrifugal pump with a flow range of 0–29 litres per minute. Cold water is supplied from the laboratory mains or an optional chilling unit. Two flow meters — one for hot water and one for cold water — each cover a range of 1 to 7 litres per minute. A control valve regulates cold water flow, and a regulation pressure valve set at 0.6 bar prevents excess pressure in the exchanger. Four flexible connecting tubes allow rapid interchange of heat exchanger modules. The structural frame is constructed from anodised aluminium with an insulated HDF wood panel; all water-contact parts are manufactured from PVC, brass, copper, or stainless steel. A front panel diagram with laser-engraved labelling provides a schematic representation of the real unit layout. Temperature is monitored by one K-type thermocouple dedicated to the temperature controller (−100°C to 400°C) and six additional K-type thermocouples (−100°C to 400°C) distributed across the system. Measured values are displayed on digital indicators on the panel and can simultaneously be transmitted to a PC via USB/Ethernet when the DAQ option is selected. The heat exchanger service unit is designed to work exclusively as the service base; at least one heat exchanger module must be ordered separately to conduct experiments.
The Saturation Pressure ThermoFlux – 7069 is a bench-top laboratory apparatus designed to demonstrate the relationship between saturation pressure and boiling point temperature of water across a range of absolute pressures. Equivalent to a Marcet Boiler, the unit adds a throttling calorimeter and a pipe loop for condensate return, providing a comprehensive introduction to two-phase thermodynamics.
Students can generate saturation curves, compare results against published steam tables, and determine the dryness fraction of wet steam using the integrated throttling calorimeter. All sensors route to a USB port for optional PC data acquisition.
Product Overview
The Saturation Pressure ThermoFlux – 7069 heats pure water to its boiling point using a pair of cartridge heaters with variable power control. A sight glass on the front of the boiler allows direct observation of boiling patterns and continuous monitoring of water level.
Saturated steam leaving the top of the boiler travels around a pipe loop before condensing and returning to the base of the boiler for reheating. The operating range covers 0 to 8 bar gauge. The top limb of the pipe loop carries a K-type thermocouple, a temperature sensor, and an electronic saturation pressure sensor. A filling point at the bottom allows the loop to be filled with pure water.
A vapour offtake with an isolating valve diverts steam through a throttling calorimeter. As steam expands to atmospheric pressure, a second K-type thermocouple measures the post-expansion temperature, enabling calculation of the dryness fraction. A pressure relief valve is set to operate if pressure exceeds the working limit; a Bourdon gauge remains operational when power is disconnected.
All power supplies, signal conditioning, and circuitry are contained in an electrical console with current protection devices and an RCD for operator safety. Sensor readings are displayed on a common digital meter. All signals are routed to a USB port for optional connection to a PC using an optional parallel interface and educational software package.
The Combined Convection and Radiation ThermoFlux – 7073 is a small-scale laboratory accessory designed to introduce students to the principles of combined convection and radiation heat transfer from a horizontal heated cylinder. The unit operates in both free convection and forced convection modes, enabling analysis of the combined effects at varying surface temperatures and air velocities.
Measurement of the cylinder surface temperature and the electrical power supplied allows comparison of combined heat transfer effects with theoretical values. The dominance of convection at lower surface temperatures and the dominance of radiation at higher surface temperatures can be demonstrated directly.
Product Overview
The Combined Convection and Radiation ThermoFlux – 7073 comprises a heated cylinder mounted in a vertical air duct with a centrifugal fan at the base. The fan provides variable air flow over the cylinder, enabling study of free and forced convection conditions. A manually adjustable throttle plate permits the air velocity to be varied. On the computer-controlled unit, the air flow is electronically adjustable over the range 0 to 10 m/s by a variable-speed fan; otherwise it is manually adjustable.
The heated cylinder uses a rod heater rated at 100 W at 24 V DC, with a diameter of 10 mm and a length of 70 to 80 mm. The surface of the cylinder is coated with heat-resistant paint that provides a consistent emissivity close to unity. The mounting arrangement for the cylinder in the duct is designed to minimise loss of heat by conduction to the duct wall. The air blower provides air velocity up to 15 m/s.
A K-type thermocouple attached to the wall of the cylinder at mid position measures the surface temperature under varying operating conditions. A K-type thermocouple in the outlet duct measures the ambient air temperature upstream of the heated cylinder. An air velocity sensor within the fan outlet duct measures the air velocity in the duct. Sensor readings enable determination of combined convection and radiation heat transfer coefficients and comparison with published theoretical values.
All sensor signals are available for optional connection to a PC using an optional DAQ software package developed in the National Instruments LabVIEW environment. A comprehensive instruction manual is included.
The Perfect Gas Law Apparatus ThermoFlux – 7077 is a small-scale bench-top unit designed for experimental investigation of the perfect gas law apparatus principles, covering the first law of thermodynamics and the pressure, volume, and temperature relationships for air. Two transparent vessels connected by a large-bore pipe and valve, together with an integral air pump, enable a range of gas expansion and compression experiments.
Air is used as the test gas. The pump can pressurize one vessel and evacuate the other simultaneously. Additional valves allow the vessels to be operated singly or in combination, including venting to atmosphere and controlled transfer between a pressurized vessel and an evacuated vessel.
Product Overview
The Perfect Gas Law Apparatus ThermoFlux – 7077 consists of two transparent vessels: a large vessel with an approximate volume of 18.5 litres and a smaller vessel with an approximate volume of 10.5 litres. The vessels are connected by a large-bore pipe and valve with an integral air pump. The pump pressurizes one vessel while evacuating the other.
Additional valves provide three operating configurations: vessels in isolation, venting to or from atmosphere, and a combined arrangement where the pressurized vessel vents into the evacuated vessel. This range of configurations enables direct observation of perfect gas law apparatus behaviour including transient pressure and temperature responses.
Fast-response thermocouple sensors are located in each vessel to record air temperatures. Individual pressure transducers record chamber pressures. Two pressure gauges, one per vessel, cover a range of -1 to 4 bar. Two temperature sensors, one per vessel, cover a range of -100 to 400°C. Pressure relief valves prevent over-pressurization in the pressurized vessel. Pressure switches limit operating pressures to safe levels.
The vessels and interconnecting pipework are constructed from impact-resistant plastic. A control box digitally displays air temperatures in both vessels. The unit supports optional continuous PC monitoring of pressure and temperature changes. The air pump is available in manual or optional computer-controlled versions.
The Nozzle Pressure Distribution ThermoFlux – 7103 is a laboratory apparatus for measuring pressure curves in convergent and convergent-divergent (de Laval) nozzles and for studying the actual flow of compressible fluids. The unit demonstrates nozzle pressure distribution across subsonic, supersonic, and shock wave velocity ranges using air as the working fluid.
Three interchangeable brass nozzles are provided: one convergent nozzle and two de Laval nozzles with short and long nozzle extensions. The unit also demonstrates the choking effect, where the mass flow rate ceases to increase upon reaching the critical pressure ratio.
Product Overview
The Nozzle Pressure Distribution ThermoFlux – 7103 uses compressed air as the working compressible fluid. Air flows through a selected nozzle and is accelerated, with the nozzle pressure distribution recorded in the direction of flow over several measuring points. The air pressure upstream and downstream of the nozzle can be independently adjusted.
A compressed air regulator with a control range of 0 to 8.6 bar adjusts the upstream supply pressure. A needle valve on the flow meter adjusts the back pressure downstream of the nozzle. The unit accepts a maximum compressed air supply of 10 bar with an approximate air consumption of 5 g/s.
Three brass nozzles with pressure measurement points are included: one convergent nozzle for subsonic investigations, one de Laval nozzle with a short nozzle extension, and one de Laval nozzle with a long nozzle extension for supersonic and shock wave studies. Instruments include a manometer and a digital temperature display upstream and downstream of the nozzle, as well as a rotameter for flow measurement.
Temperature is measured across the range -100 to 400°C. Pressure is measured at 10 points across the range -1 to 9 bar. Flow rate is measurable up to 25 m³/h. Optional DAQ software in the National Instruments LabVIEW environment enables PC-based data recording, storage, and analysis.
The Thermal Expansion Apparatus ThermoFlux-26 is a precision laboratory instrument for determining the linear thermal expansion of brass, copper, and aluminium as a function of temperature. This thermal expansion apparatus uses a dilatometer method with a digital dial gauge to measure dimensional change in 500 mm expansion rods across three materials. Students investigate the direct relationship between temperature change, material properties, and change in length.
Product Overview
The ThermoFlux-26 is designed for quantitative measurement of linear expansion in metallic rods subjected to controlled temperature variation. Three expansion rods, one each in brass, copper, and aluminium, are each 500 mm in length. Temperature is applied via a heating system with a 2-litre tank capacity and a heating power range of 500 W to 1,000 W. Dimensional change is measured using a digital dial gauge with a range of 0 to 20 mm and a resolution of 0.01 mm, providing precise tracking of rod elongation at each temperature step.
The apparatus supports determination of linear expansion coefficients for each material, investigation of the relationship between change in length and overall rod length, and study of equilibrium spacing and thermal capacity. Results are obtained directly from the dial gauge readings against measured temperature.
An optional DAQ software package, developed in the National Instruments LABVIEW environment, is available for automated data acquisition and analysis. When the software option is selected, a set of electronic sensors is included. The software is compatible with any Windows operating system.
The Thermal Conductivity Apparatus ThermoFlux-25 is a laboratory instrument for measuring heat flow across a consistent 100°C temperature differential through five common building and insulation materials. This thermal conductivity apparatus uses a steam chamber as the hot reservoir and a block of ice as the cold sink, with the rate of ice melt into water serving as the quantifiable measure of heat transfer through each test sample. Students determine thermal conductivity values for Bakelite, wood, aluminium, Sheetrock, and Masonite using identical sample geometry across all tests.
Product Overview
The ThermoFlux-25 operates on a straightforward principle: a test sample is clamped between a steam chamber on one side and a block of ice on the other. The steam chamber maintains a constant temperature, creating a 100°C differential across the sample. Heat flows from the steam, through the test material, and into the ice. The rate of ice melting, collected as water into a glass beaker, provides a direct, measurable indicator of the thermal conductivity of each material.
Five sample materials are supplied: Bakelite, wood, aluminium, Sheetrock, and Masonite. Each sample is 100 x 100 mm in face dimension and 5 mm thick. Wood, Masonite, and Sheetrock samples are covered with a thin aluminium sheet for waterproofing, ensuring effective thermal contact during experiments. The steam reservoir is fabricated from stainless steel with a 2-litre capacity and is positioned high above the lab table to eliminate risk of heat damage to the work surface. Meltwater flows directly into the measuring beaker, keeping the lab table free of spillage.
Two steel ice molds, each with a capacity of 300 to 400 ml, are supplied for preparing ice blocks. A glass beaker of 500 ml capacity collects meltwater for measurement. A measuring scale with a range of 0 to 100 N and a resolution of 0.1 N is included. The complete assembly is mounted on a stand with insulating pads.
An optional small steam generator (ThermoFlux-25) is recommended for operation. Optional DAQ software developed in the National Instruments LABVIEW environment is also available, compatible with any Windows operating system. Electronic sensors are included when the software option is selected.
The Small Steam Generator ThermoFlux-24 is a compact, variable-power laboratory heat reservoir designed to provide continuous steam at a constant temperature. This small steam generator boils 3/4 litre of water in ten minutes and delivers continuous steam output at up to 2.5 kg/h. Dual steam ports, a 1-litre water capacity, and variable power from 0 to 3,000 W make it a practical and flexible steam source for laboratory thermal experiments.
Product Overview
The ThermoFlux-24 is built for reliable, consistent steam supply in laboratory settings. It holds 1 litre of water and heats it using an internal electric heater, eliminating any open flame or exposed coil hazard. Variable power adjustment from 0 to 3,000 W allows the user to control steam flow rate to match experimental requirements. Continuous steam output reaches up to 2.5 kg/h.
Two steam ports allow the unit to supply two laboratory groups simultaneously from a single generator. A rubber stopper provides a tight seal and incorporates a safety pressure release function. A low water warning light alerts the user before the water level becomes critically low. An extra-wide base provides stability and resistance to tipping during operation. An included baster allows safe removal of hot water during experiments.
This small steam generator is suitable as a heat reservoir for use with compatible laboratory apparatus, including the Thermal Conductivity Apparatus ThermoFlux-25.
The Extended Surface Heat Transfer Module ThermoFlux – 7049/4 is a laboratory module for investigating temperature distribution and heat transfer along a cylindrical pin fin under combined free convection and radiation conditions. This extended surface heat transfer module uses a 350 mm brass pin fin with 9 thermocouple positions and a 100 W heater to enable direct measurement and comparison with theoretical fin analysis. Students determine thermal conductivity of the rod material and calculate combined convective and radiative heat transfer from the fin surface.
Product Overview
The ThermoFlux – 7049/4 centres on a cylindrical brass pin fin element, 10 mm in diameter and 350 mm in length, instrumented with 9 thermocouple positions along its length. The fin is heated at its base by a 100 W heater. Temperature readings at each of the 9 positions along the rod allow students to plot the full axial temperature distribution and compare measured profiles directly against theoretical predictions from analytical fin equations.
Extended surfaces, commonly referred to as fins, transfer heat from a body by combining conduction within the solid with convection and radiation from its outer surface to the surrounding environment. Pin fins, characterised by a high length-to-diameter aspect ratio, are widely used in cooling systems for electrical appliances such as computer power supplies and substation transformers, as well as in engine cooling applications. The ThermoFlux – 7049/4 replicates this configuration at laboratory scale for structured experimental analysis.
Three core experiments are supported: measurement of axial temperature distribution with theoretical comparison, determination of thermal conductivity of the brass rod material, and calculation of combined free convection and radiation heat transfer from the extended surface with comparison to theoretical predictions.
The module requires the Heat Transfer Service Unit ThermoFlux – 7049 for operation.
The Radiation Heat Transfer Module ThermoFlux – 7049/3 is a laboratory module for demonstrating and verifying the fundamental laws governing thermal radiation heat transfer. This radiation heat transfer module provides an electrically heated radiant source rated at 300 W with a maximum temperature of approximately 460°C, a set of seven metal specimens across three materials, and an aperture plate assembly for structured experimental investigation. Students verify the inverse square law, Stefan-Boltzmann Law, Kirchhoff’s Law, emissivity, absorptivity, and geometric view factor relationships through direct measurement.
Product Overview
The ThermoFlux – 7049/3 is designed to illustrate how thermal radiation, as a mode of heat transfer distinct from conduction and convection, behaves according to established physical laws. A 300 W electrically heated plate serves as the radiant source, reaching a maximum temperature of approximately 460°C. A radiometer measures radiation intensity at the specimen surface. Seven metal specimens in three materials, stainless steel, aluminium, and copper, each measuring 135 x 145 mm, provide a range of surface finishes and coatings for comparative emissivity and absorptivity measurement.
The specimen set covers bright, matt anodized, nickel-plated, and high-temperature painted surfaces. Stainless steel specimens oxidise over time due to high operating temperatures, providing an additional surface condition for study. Aluminium specimens are supplied in three variants: matt anodized on both sides, painted on both sides with high-temperature paint, and matt anodized with one painted side. Copper specimens are supplied in two variants: nickel-plated and bright, the latter also oxidising over time.
An aperture plate assembly, consisting of two plates with insulation on one side, is used in view factor experiments. The insulated surface faces the heated source during experiments to control radiation geometry. All experiments compare measured results against theoretical predictions from the relevant radiation equations.
The module requires the Heat Transfer Service Unit ThermoFlux – 7049 for operation.
The Linear Heat Conduction Module ThermoFlux – 7049/1 is a laboratory module for the experimental investigation of one-dimensional, steady-state and unsteady-state linear heat conduction through solid materials. This linear heat conduction module uses an insulated brass heated section, a water-cooled brass cold section, and four interchangeable test specimens instrumented with nine thermocouples to enable direct measurement of temperature distribution, thermal conductivity, contact resistance, and the Overall Heat Transfer Coefficient across single and composite material configurations.

Product Overview
The Recycle Loops ThermoFlux – 7089 consists of a through pipe conveying water from a cold-water supply to a drain, with a loop of pipework connected between the supply and drain connections. The recycle loop incorporates a variable-speed gear circulating pump (12 lpm, 4 bar, 180 W) and a 0 to 3000 W electric heater with over-temperature protection. A pressure regulator with filter at the inlet minimizes the effect of fluctuations in the cold-water supply pressure.
Loop flow rate is variable from 0 to 7 l/min, and the passing flow of water is also variable from 0 to 7 l/min. The heater can be switched on or off to generate step changes for transient response investigation. A waste-free quick disconnection fitting enables a short pipe or a 1 L reservoir to be connected in series with the recycle loop to change the loop volume and demonstrate the effect of residence time. Different lengths of flexible tubing can also be connected in series for further residence time variation.
Water temperatures at the inlet, outlet, and within the recycle loop are measured by K-type thermocouples. Flow rates at the inlet, outlet, and corresponding loop locations are measured by miniature turbine-type flow sensors. Flow sensors at both inlet and outlet demonstrate that these two flow rates remain equal regardless of recycle rate. All power supplies and signal conditioning circuitry are housed inside the control panel. The console includes a digital meter displaying temperatures and flow rates. Signals can be sent to DAQ via LAN or USB port for PC connection. An RCD and appropriate current protection devices are fitted for operator protection.

The nozzles are designed to operate at different theoretical expansion ratios and can be exchanged rapidly.
The unit measures both the reaction force (thrust) of the fluid at the nozzle and the action force at the baffle plate. Force measurement is performed by deformation of a flexion pipe, with a measuring range of 0 to 5 N. The distance between the baffle plate and the nozzle is adjustable. Air intake is adaptable according to the experiment layout. A compressed air regulator with a control range of 0 to 10 bar adjusts the pressure downstream of the nozzle. A needle valve on the flowmeter adjusts the back pressure.
Instrumentation includes a manometer and digital temperature display upstream and downstream of the nozzle, as well as a flowmeter. Measuring ranges cover temperature (-100 to 400°C), pressure (2x 0 to 10 bar), mass flow (0.7 to 8.3 g/s), and force (0 to 5 N). Operating conditions can be varied rapidly to generate results across a wide range of pressure ratios. Optional DAQ software enables PC-based data acquisition in a LabVIEW environment.
Product Overview
The unsteady state heat transfer unit consists of a stainless steel water bath with an integral flow duct and an external water circulating pump. The bath has a capacity of approximately 30 liters. It is heated by a thermostatically controlled 3 kW electric heating element installed in the base of the bath.

This tray dryer features four corrosion-resistant removable trays, an adjustable-speed axial fan, a 0 to 3500 W controlled heater, a digital balance, combined humidity and temperature sensors before and after the drying zone, and an air velocity sensor, providing a complete platform for drying curve analysis and energy and mass balance evaluation.
Product Overview
The Tray Dryer ThermoFlux – 7101 consists of a rectangular drying channel approximately 2000 mm in length with internal dimensions of 350 x 350 mm. An axial flow fan at the left end draws air into the duct. Fan speed is adjustable, with a maximum output of 700 m³/h and a maximum speed of 950 min⁻¹, consuming 33 W. A bank of electric heaters downstream of the fan raises the air temperature, with power adjustable from 0 to 3500 W and a temperature limiter included. A transparent door in the drying channel allows the drying process to be observed directly.
Four corrosion-resistant drying trays measuring 300 x 300 mm each are placed in the channel. The trays containing the solid to be dried are exposed to the airflow, which heats the solid and removes released moisture. A rack of trays is suspended from a digital balance above the duct. The balance has a measuring range of 0 to 10,000 g with a resolution of 0.1 g and an application temperature range of 0 to 75°C, enabling continuous monitoring of weight changes due to moisture evaporation.
One combined temperature and humidity sensor is positioned before and one after the air flow passes over the solid, measuring humidity (0 to 100% rel.) and temperature (-100 to 400°C) at both locations.

All measured parameters, including weight changes, humidity, temperature, and air velocity, can be transferred directly to a PC via optional DAQ software. A battery-operated digital stopwatch is included.
The Exhaust Gas Calorimeter ThermoFlux – 7105 is a laboratory apparatus for determining the thermal exhaust gas losses of internal combustion engines using calorimetric measurement. The exhaust gas calorimeter achieves largely complete and loss-free heat exchange between the exhaust gas and a cooling water circuit, enabling accurate calculation of the engine energy balance.
The unit consists of an insulated stainless steel tank through which exhaust gas flows from bottom to top, transferring its heat to a looped finned pipe heat exchanger carrying cooling water. Four temperature sensors and a flow meter record all relevant parameters; values are displayed digitally via a measuring amplifier.
Product Overview
The Exhaust Gas Calorimeter ThermoFlux – 7105 determines the amount of heat contained in the exhaust gas from test engines. The calorimeter consists of a finned pipe heat exchanger housed in an insulated stainless steel tank. Exhaust gas enters at the bottom of the tank and flows upward, giving up its heat almost completely to cooling water circulating through the finned pipe.
The finned pipe is arranged in loops to maximise the heat exchange area. The heat exchange area on the exhaust gas side is 1.169 m². The heat exchange area on the water side is 0.164 m². This large ratio ensures thorough and near-complete heat transfer from the exhaust gas to the cooling medium, which is the core operating principle of the exhaust gas calorimeter.
Four temperature sensors record exhaust gas inlet and outlet temperatures and water inlet and outlet temperatures. A flow meter records the cooling water flow rate. All measured values are recorded electronically and displayed digitally using a measuring amplifier. The engine is connected to the calorimeter via an exhaust gas hose. The specific heat capacity of the exhaust gas can also be determined from the recorded data.
The Heat Conduction and Convection ThermoFlux – 7106 is a laboratory apparatus designed for basic experiments on heat conduction and convection, two of the three fundamental forms of heat transfer. Six interchangeable metal samples, each functioning as a cooling fin, are heated at one end and dissipate heat through conduction along their length and convection to the surrounding air.
Six fans below the sample provide continuously adjustable forced air flow, enabling comparison between free convection with still air and forced convection with flowing air. The effect of different materials and different sample lengths on heat transfer can be directly compared. Microprocessor-based instrumentation is integrated into the housing; heating power and fan speed are controlled and displayed via software.
Product Overview
The Heat Conduction and Convection ThermoFlux – 7106 centres on six metal samples: two long samples (copper and steel) with a heat-dissipating length of 154 mm and a heat transfer area of 48.4 cm², and four short samples (copper, aluminium, brass, and steel) with a heat-dissipating length of 104 mm and a heat transfer area of 32.6 cm².
Each sample is placed on a heater rated at 30 W with a temperature limit of 160°C. The sample is heated at one end; heat is conducted along its length and dissipated to the environment, replicating the behaviour of a cooling fin. Six fans with a maximum flow rate of 40 m³/h, nominal speed of 14,400 min⁻¹, and a power consumption of 8 W per fan provide adjustable forced air flow around the sample, enabling heat conduction and convection experiments under both free and forced convection conditions.
Eight temperature sensors measure temperatures across the range -100 to 400°C. Flow velocity is measured from 0 to 10 m/s. Heating power is measured and controlled over 0 to 30 W. All measured values, including temperatures, heating power, and air velocity, are displayed in the software. The integrated microprocessor-based instrumentation requires no additional external devices or error-prone wiring. Optional DAQ software in the National Instruments LabVIEW environment enables PC-based data acquisition on any Windows system.

The Film & Dropwise Condensation ThermoFlux – 7097 is a laboratory unit specially designed to enable students to visualise and investigate both filmwise and dropwise condensation processes within a transparent glass test section. This film and dropwise condensation unit includes two water-cooled copper and brass condenser tubes with different surface treatments, a 3 kW controlled heater, a water jet vacuum ejector, six thermocouples, two rotameters, and a pressure gauge for comprehensive condensation heat transfer analysis.
Product Overview
The Film & Dropwise Condensation ThermoFlux – 7097 is built around a transparent glass cylinder test section that allows direct visual observation of the condensation process. Two water-cooled condenser tubes are installed inside the tank: one with a gold-plated surface to realise dropwise condensation and one with a natural finish surface to realise filmwise condensation. Both condensers are fabricated from copper and brass alloys, have a diameter of 15 mm and an effective length of 95 mm, and are each fitted with a thermocouple.
In filmwise condensation, a film of condensate forms and spreads over the wettable natural finish surface, increasing in thickness as vapour continues to condense. This liquid film acts as a poor thermal conductor, contributing to thermal resistance. In dropwise condensation, the non-wettable gold-plated surface causes condensate to form as spherical beads that grow, coalesce, and flow downward, leaving bare surface areas with very low thermal resistance and enabling high heat fluxes.
A 3 kW electric heater with a temperature controller adjusts the boiling temperature within the tank. A water jet vacuum ejector evacuates the tank to enable operation at sub-atmospheric pressures. A pressure switch and safety valve are fitted for safe operation. Six thermocouples with a digital temperature indicator (range: -100 to 400°C) measure temperatures across the system. A pressure gauge with a range of 0 to 6 kg/cm² measures tank pressure. Two rotameters measure the cooling water flow rates for both condensers independently.

It provides a complete experimental platform for studying triaxial stress states as applied to pressure vessel and pipeline design.
Product Overview
The Thick Wall Cylinder FortiTestX-41 addresses the uneven stress distribution across the wall thickness that distinguishes thick-walled pressure vessels from thin-walled ones. Under internal pressure, this thick wall cylinder enters a triaxial stress condition, with radial, circumferential, and axial stresses and strains developing simultaneously. Because internal strains cannot be measured directly, the unit uses surface and groove-mounted strain gauges to estimate the full internal stress and strain state. The apparatus consists of a two-part oil-filled aluminium cylinder sealed hermetically. Internal pressure is generated by a hydraulic cylinder and spindle arrangement, and displayed on a pressure gauge graduated to 100 bar, with a maximum operating pressure of 7 N/mm² (70 bar). An eccentric flat groove is machined between the two cylinder sections, where strain gauges are bonded at various radial positions. Additional strain gauges are placed on both the inner and outer surfaces of the cylinder. Ten strain gauges in total, configured as half-bridges at 350 Ohm with a gauge factor of 2.00 +/- 1%, provide complete documentation of the radial, hoop, and axial strain state. A measuring amplifier with 10 V supply reads the signals directly. Optional Windows-based Software FX-41 loads measured values for visual evaluation and graphical Mohr’s Circle representation of the triaxial stress condition. Elasticity equations are applied to convert measured strains into direct stresses.

A moveable piston controlled by a threaded spindle bolt seals one end of the cylinder, allowing selection between two load conditions: the uniaxial stress state of an open-ended pipe, and the biaxial stress state of a sealed container such as a boiler tank. Internal pressure is generated by a hydraulic hand pump fitted with a factory-preset pressure release valve, and is indicated by a pressure gauge graduated to 30 bar. Oil fills the sealed cylinder interior. Five strain gauges are bonded to the outer surface of this thin wall cylinder in half-bridge configuration at angles of 0°, 30°, 45°, 60°, and 90° to the cylinder axis, covering both hoop and longitudinal stress and strain positions. A universal strain gauge amplifier with a 10 V supply reads measured strains directly.

Product Overview
The Unsymmetrical Cantilever Apparatus FortiTestX 20 is a self-contained tabletop strength of materials lab equipment unit for the study of general and unsymmetrical bending, torsion moments, and shear centre behaviour in straight cantilever beams. The primary column is firmly secured at its lower end to a rigid framework, with a loading head at the top that rotates freely at various angles around the vertical axis of the beam. Four interchangeable steel beam specimens are supplied: one rectangular section, one L-shaped section, one U-shaped section, and one I-shaped section, all with a deformed beam length of 500 mm. Beams are clamped at one end in a solid support and a vertical point load is applied to the free end using a set of calibrated weights via a lever fastened to the beam on the rotating head. The angular position of the loading head is marked on a graduated disc for precise and repeatable angular positioning. Load application point offset is adjustable from 0 to 25 mm on either side of the force application point using locating bolts, enabling combined torsion and bending loading required for shear centre investigation. Two dial gauges mounted perpendicular to each other on the head measure vertical and horizontal end deflections across a 0 to 10 mm range with 0.01 mm resolution. Adjustment bolts allow precise zeroing of both dial gauges before each test. The open bench layout of the unsymmetrical cantilever apparatus allows beam bending to be clearly observed from the front throughout the experiment.

A water-cooled condenser coil of mean surface area approximately 0.032 m² is mounted at the top of the chamber for condensation of vapour generated by the volatile solvent R141b, which boils at low pressure. Sensors are provided for measurement of heater surface temperature, R141b liquid temperature, R141b vapour temperature, cooling water inlet and outlet temperatures, chamber pressure, and cooling water flow rate. Voltage and current meters measure electrical input to the heating element directly. The unit enables production of Heat Flux against Temperature Difference, Heat Transfer Coefficient against Temperature Difference, and Critical Heat Flux against Saturation Pressure graphs across all three modes of boiling heat transfer. It may also be used as a Marcet boiler to provide the saturation pressure–temperature relationship for R141b over a limited pressure range, and demonstrates Dalton’s Law of Partial Pressures. A charging and drain valve fitted to the lower end plate allows R141b charging and discharge. A comprehensive safety system includes a high-temperature cut-out at 170°C, a high-pressure cut-out at 2.2 kg/cm², a pressure relief valve set at 2.5 kg/cm², and a fused electrical circuit breaker with mains switch and indicating lamp.

The ThermoFlux – 7015 Pressure Measurement Bench provides a structured platform for studying pressure and vacuum measurement across a range of instrument types. The manometer panel integrates two tube manometers (U-tube and inclined tube), two dial manometers (positive and negative range Bourdon tube), and one digital pressure transmitter with display — allowing direct comparison of measurement methods under identical test conditions.
Test pressures in the millibar range are generated using the supplied plastic syringe or hand pump. All manometers can be interconnected via flexible connecting hoses, enabling gauge pressure and vacuum measurement configurations. The bench also serves as a calibration training tool: deviations between a measuring instrument and a reference standard are identified, recorded, and corrected.
The integrated Dead Weight Pressure Calibrator provides an introduction to manometer calibration fundamentals. It consists of a precision-machined piston and cylinder assembly mounted on levelling screws. Known dead weights are loaded onto the piston rod, which is rotated during operation to minimise friction. The ratio of applied force to piston cross-sectional area produces a defined, traceable test pressure transferred hydraulically to a Bourdon tube gauge. An error curve is drawn by comparing gauge readings against known applied pressures. Both dial and Bourdon tube manometers can be calibrated using this dead-weight piston method.

Product Overview
The ThermoFlux – 7027 Free and Forced Convection Heat Exchanger provides a structured experimental platform for studying the fundamental mechanisms of convective heat transfer as applied to industrial heat exchanger design. The apparatus centres on a vertical air duct (120 × 120 mm flow cross-section, 1000 mm height) into which plug-in heated surface modules of known dimensions are presented to the air stream for detailed thermal analysis.
Three standard heating modules are supplied — a finned surface, a pipe bundle, and a flat surface — each rated at 150 W. An axial fan mounted at the top of the duct delivers the controlled air stream for forced convection experiments; free convection studies are conducted with the fan inactive. Each module may also be used independently on the bench in horizontal orientation to establish free convection coefficients outside the duct.
The control panel integrates temperature measurement, continuously variable heating power control (0–100 W output with direct watt readout), and fan speed control. Temperature is measured to a resolution of 0.1°C using thermocouple sensors with direct digital readout in °C. Air velocity is measured using a portable anemometer mounted on the duct. All heating elements are subject to a 90°C temperature limitation.
Optional modules — a plain cylinder, a cylinder with heating foil for local heat transfer investigation, and a plate surface — extend the experimental scope. The optional ThermoFlux – 7027 DAQ software, developed in the National Instruments LabVIEW environment, displays temperatures, heating power, and air velocity, and calculates results automatically.
The ThermoFlux – 7023 Boyle’s Law Apparatus provides a focused experimental platform for investigating the relationship between pressure and volume in a gas maintained at approximately constant temperature. Air is used as the test gas, requiring no specialist gas supply.
The enclosed air volume within the transparent vessel is reduced or increased by a built-in 60 W pump that displaces hydraulic oil into or out of the vessel. When volume changes occur slowly, the process approximates isothermic conditions, satisfying the requirements of the Boyle-Mariotte Law. A 3/2-way valve switches the pump between compression and expansion modes; the same compressor is also operable as a vacuum pump, extending the range of this Boyle’s Law Apparatus into sub-atmospheric pressures. Pressure is monitored via a gauge over a 0–4 bar range; volume varies over approximately 0–1.5 L; and temperature is measured electronically over –100°C to 400°C. The transparent vessel construction allows direct visual observation of the change of state throughout each experiment.
The Changes of States of Gases ThermoFlux – 7019 is a dedicated laboratory apparatus enabling students to study and experimentally verify two fundamental gas laws: the isothermic change of state (Boyle-Mariotte Law) and the isochoric change of state (Gay-Lussac’s Law). This Changes of States of Gases unit uses air as the test gas across two independent transparent vessels, each instrumented with pressure and temperature sensors for direct, quantitative observation.
The ThermoFlux – 7019 Changes of States of Gases apparatus provides a structured experimental platform for investigating thermodynamic gas behaviour under controlled conditions. The unit is divided into two functional vessels, each dedicated to a distinct gas law, operated independently or comparatively.
Vessel 1 (Isothermic — Boyle-Mariotte Law): Positioned on the left, this transparent vessel encloses a variable air volume. A built-in pump displaces hydraulic oil to reduce or increase the enclosed air volume, producing a controlled isothermic change of state. A 3/2-way valve switches between compression and expansion modes; the pump can also function as a vacuum pump. When changes occur slowly, temperature remains approximately constant, satisfying isothermic conditions. Pressure is measured over a gauge range of 0–4 bar; volume varies over approximately 0–3 L.
Vessel 2 (Isochoric — Gay-Lussac’s Law): Positioned on the right, this transparent vessel encloses a fixed volume of air. A controlled electric heater raises the gas temperature; the resulting pressure rise is measured at constant volume, demonstrating Gay-Lussac’s Law directly. Temperature and pressure are measured electronically via integrated sensors.
Both vessels share a pressure measuring range of 0–4 bar gauge and a temperature measuring range of –100°C to 400°C.

This Torsion Testing Machine 1000Nm Motorized apparatus applies torque via a motor-driven worm gear reduction mechanism, measuring test torque through a strain gauge shaft and angle of twist through an incremental encoder, with both values displayed simultaneously on digital readouts within a microprocessor-based enclosure. The FortiTestX 12 accommodates specimen lengths up to 650 mm via a sliding measurement jig and accepts specimens of different diameters through a jaw-type holder, making it the highest-capacity torsion testing machine 1000Nm motorized unit in the FortiTestX range for undergraduate and research-level engineering laboratories.
Product Overview
The Torsion Testing Machine FortiTestX 12 is a self-contained motorised benchtop unit for torsion testing of different materials — mild steel, aluminium, and brass — to specimen fracture at torque levels up to 1000 Nm. Torque is applied through a worm gear reduction mechanism driven by a motor, providing controlled, repeatable, and high-capacity torsional loading. A strain gauge bonded to the measuring shaft captures the actual test torque as an electrical signal with a resolution of 1 Nm and transmits it to the digital display. The angle of twist is measured by an incremental encoder with 0.1° resolution across a 0° to 360° incremental range, displayed simultaneously alongside torque on dedicated digital readouts housed within a secure microprocessor-based enclosure. The measurement jig slides along the frame to accommodate test rods up to 650 mm in length. Unlike lower-capacity models in the FortiTestX series, the FortiTestX 12 torsion testing machine 1000Nm motorized unit uses a jaw-type holder capable of gripping specimens of different sizes, expanding the range of testable rod diameters and profiles. Square sections on the base plate resist torsional movement during testing. Test torque, twist angle, and stiffness modulus are all measurable and processable via the optional LabVIEW-based software (FX-12), which connects to a PC via USB and runs on any Windows operating system. Live graph plotting on HMI is available as an optional feature.

The FluidoSurge-X 388 is a vertical open wind tunnel with smoke visualization, designed for demonstrating and investigating airflow around various models. A variable-speed radial fan generates vertical upward airflow through the working section, with non-toxic smoke injected via a comb for streamline visualization. Suitable for small group experiments and classroom demonstrations.
Product Overview
The FluidoSurge-X 388 is a floor-standing vertical smoke tunnel mounted on a mobile metal frame with castors. A variable-speed fan at the top draws air upward through the working section. A movable comb below the working section distributes smoke — produced by evaporating a glycol mixture in the fog generator — through 23 filaments at 7 mm spacing for uniform smoke injection. The transparent, removable working section (180 mm x 100 mm x 240 mm) has a front wall for model attachment and a black background for clear smoke trail visibility. Lamps on both sides of the working section enhance illumination. A stabilization chamber with flow straightener ensures low-turbulence flow. Fan speed controls are located on a control unit attached to the frame. Air velocity is adjustable from 0 to 5 m/s. Sound level is lower than 70 dB(A). Eleven standard models are included; aerofoil and guide vane profile angle of attack are adjustable with a scale for display.

The FortiTestX 08 Shearing Force and Bending Moment Apparatus is a benchtop experimental unit designed for the direct measurement of internal shear force and bending moment at a defined cross-section of a loaded beam. Manufactured by SCIENTICO, this apparatus is intended for use in strength of materials, structural mechanics, and civil and mechanical engineering laboratory programmes at engineering colleges, polytechnic institutes, and technical universities. It provides students with a physical demonstration of the method of sections, enabling experimental values of shear force and bending moment to be measured and compared directly against analytically calculated results from equilibrium conditions.
Product Overview
In structural analysis, static equilibrium describes the conditions under which external forces acting on a rigid body are balanced. In practice, these forces generate internal effects within the component — most significantly, shear force and bending moment. The method of sections is the standard analytical tool for determining these internal forces at any cross-section of a beam. Understanding the distribution of shear force and bending moment along a beam span is fundamental to structural design, as these quantities govern the selection of beam cross-section, material, and span configuration.
The FortiTestX 08 consists of a 1000 mm steel beam supported at two points with a clear span of 800 mm. The beam is sectioned at one-third of the span by a low-friction hinge with two degrees of freedom. This hinge replicates the internal section cut used in the method of sections and physically separates the beam into two segments at the measurement point. Two force gauges are mounted at the hinge location. The first force gauge measures the shear force directly at the section. The second force gauge acts on a fixed lever arm of 100 mm length and records the bending moment at the section. The bending moment value is calculated from the product of the force gauge reading and the lever arm length.
Adjuster nuts on the two force gauges allow the beam to be levelled horizontally before loading, compensating for any initial misalignment or gauge pre-load. Point loads are applied using calibrated weight hangers at positions determined by a 1 mm graduated steel rule of 1000 mm length. Single point load and multiple point load configurations are both supported. Students calculate the expected shear force and bending moment values from equilibrium conditions, then compare these against the directly measured force gauge readings, constructing shear force and bending moment diagrams from the experimental data.

The FortiTestX 05 Hooke’s Law Apparatus is a freestanding experimental unit designed to investigate the elastic behaviour of tension springs and the dynamics of spring-mass systems. Manufactured by SCIENTICO, this apparatus is intended for use in strength of materials, physics of materials, and mechanical engineering laboratory programmes at engineering colleges, polytechnic institutes, and technical training centres. It supports both static experiments — measuring spring extension under incremental loads — and dynamic experiments involving the oscillation frequency of a spring-mass system, making it one of the more versatile single-spring laboratory units in the FortiTestX series.
Product Overview
Hooke’s Law defines the elastic behaviour of materials and mechanical components under load. It states that within the elastic limit of a body, the extension produced is directly proportional to the applied load. This principle underpins the design of springs used across engineering applications — from precision instruments and weighing systems to vibration isolation and energy storage mechanisms.
The FortiTestX 05 consists of a helical tension spring suspended from a metal stand fitted with an integral millimetre-graduated scale of 1000 mm length. The free end of the spring carries a hanger and a pointer. As calibrated weights are added to the hanger, the spring extends and the pointer indicates the corresponding extension directly on the scale. This direct-reading configuration eliminates the need for secondary measurement instruments for basic load-extension experiments.
The apparatus supports four distinct experimental configurations. In the first, a single spring is loaded incrementally and the extension is recorded at each load step to verify the linear relationship between force and elongation. In the second, two tension springs are connected in series, and the combined system stiffness is measured and compared against the theoretical prediction. In the third, the spring constant is determined numerically from the load-extension data. In the fourth, a mass is suspended from the spring and set into oscillation, allowing students to investigate how the spring constant influences the natural frequency of the spring-mass system — an introduction to simple harmonic motion.
Twelve helical tension springs are supplied across two outer diameter groups, each available in six wire diameters, enabling a systematic study of the effect of wire diameter on spring stiffness within a controlled experimental setting.

The FortiTestX 07 Continuous and Indeterminate Beams Apparatus is an electronically instrumented experimental unit designed for the investigation of beam deflection, support reactions, and elastic line behaviour under statically determinate and indeterminate conditions. Manufactured by SCIENTICO, this apparatus is intended for use in strength of materials, structural mechanics, and civil and mechanical engineering laboratory programmes at engineering colleges, technical universities, and research laboratories. It advances beyond dial gauge-based beam testing by incorporating electronic load cells at each support position, providing direct digital measurement of vertical reaction forces and enabling a broader range of structural analysis experiments.
Product Overview
Continuous and indeterminate beams are encountered throughout structural engineering practice — in bridge girders, building frameworks, and machine structures. Unlike statically determinate beams, indeterminate beams have more support reactions than can be resolved through equilibrium equations alone, requiring compatibility conditions and methods such as the force method or the principle of virtual work for full analysis. Experimental verification of these analytical methods is a core component of advanced structural mechanics and strength of materials courses.
The FortiTestX 07 is mounted on a compatible test frame. Up to three supports can be positioned under the beam at adjustable locations along the span, allowing single-span, dual-span, and triple-span configurations to be established. Three of the supports incorporate electronic load cells with knife-edge contacts. Each knife-edge support can be set to either a fixed position or allowed to sink by a defined displacement, enabling students to study the effect of support settlement on reaction forces and beam deflection. Two additional supports with clamping fixtures establish fixed-end boundary conditions for cantilever and other indeterminate configurations. All load cells are connected to a digital force display device, providing continuous real-time reaction readings.

The FortiTestX 06 Deflection of Beam Apparatus is a comprehensive benchtop experimental unit designed for the investigation of beam deflection, slope measurement, and support reaction determination under various loading and support conditions. Manufactured by SCIENTICO, this apparatus is intended for use in strength of materials, structural mechanics, and civil and mechanical engineering laboratory programmes at engineering colleges, technical universities, and research laboratories. It supports both statically determinate and statically indeterminate beam configurations, enabling students to compare experimental measurements directly against analytical results derived from differential equations and the Area Moment Method.
Product Overview
Beams are fundamental structural elements in both civil and mechanical engineering. A beam resists transverse loading primarily through bending, generating internal compressive, tensile, and shear stresses along its length. Understanding beam deflection behaviour — how a beam deforms under load as a function of its geometry, material, and support conditions — is a core competency in structural analysis and materials science education.
The FortiTestX 06 is housed in an anodized aluminum section frame that contains the complete experimental setup. The investigation beam is supported by up to three articulated, height-adjustable supports, each fitted with a built-in force gauge that provides direct readings of support reactions. Support height adjustment compensates for the dead weight of the beam under investigation. Two additional supports with clamp fixing allow cantilever and other fixed-end configurations to be established. The points of load application are adjustable along the beam span, and up to four sets of calibrated weights can be applied simultaneously — either as point loads using load hangers or as uniform loads using multiple weights with adjustable riders.
Three dial gauges measure deflection and slope at selected points along the beam. The apparatus is supplied with fifteen beam sections across five materials — stainless steel, brass, aluminum, mild steel, and copper — each available in three cross-sectional thicknesses (19 x 3 mm, 19 x 5 mm, and 19 x 6 mm). This range enables systematic investigation of the influence of elastic modulus and cross-sectional geometry on beam deflection behaviour. All components are organised and stored in a dedicated storage system integrated with the frame. Optional LabVIEW-based software is available for data logging and results processing.

The FortiTestX 04 Combined Bending and Torsion Apparatus is a benchtop experimental unit designed to verify equivalent stress hypotheses from materials science through controlled multi-axis loading of metal specimens. Manufactured by SCIENTICO, this apparatus is intended for use in strength of materials, mechanics of solids, and materials science laboratory programmes at engineering colleges, mechanical engineering departments, and research laboratories. It enables students to apply defined combinations of bending and torsion to standardized specimens and compare experimental results against established stress theories, including the direct stress hypothesis and the shear stress hypothesis.
Product Overview
In engineering design and materials science, components are rarely subjected to a single type of loading. Combined bending and torsion is a common real-world loading condition encountered in shafts, axles, and structural members. Equivalent stress theories — such as the maximum normal stress hypothesis and the maximum shear stress hypothesis — provide frameworks for predicting the yield point of a material under such combined loading conditions. Experimental verification of these theories is a fundamental exercise in advanced strength of materials courses.
The FortiTestX 04 applies a load moment to a metal specimen by attaching calibrated weights to defined positions on the perimeter of a circular load plate, which functions as a lever arm. The specimen is clamped at the centre of the plate. The angular position of the load weight can be adjusted in 10-degree steps around the plate, enabling pure bending, pure torsion, or any defined combination of both to be applied to the specimen. This angular adjustment is the central feature of the apparatus, as it allows systematic variation of the bending-to-torsion ratio while keeping the total load moment constant.
Deformation is measured at the point of maximum deflection, positioned diametrically opposite to the point of load application. This arrangement minimises measurement error introduced by deformation of the test apparatus itself under load. The dead weight of the circular load plate and the weight of the load hanger are compensated by a counterweight, ensuring that only the intentionally applied load contributes to the specimen stress state. Specimens are available in four materials — steel, copper, brass, and aluminum — allowing comparative study of yield behaviour across different metals under identical loading conditions.

The FortiTestX 03 Extension and Compression of Spring Apparatus is a wall-mounted experimental unit designed to demonstrate Hooke’s Law through both compressive and tensile loading of helical springs. Manufactured by SCIENTICO, this apparatus is intended for use in strength of materials and mechanics of solids laboratory courses at engineering colleges, polytechnic institutes, and technical training centres. By accommodating both spring types within a single unit using a common loading mechanism, it provides a more comprehensive study of spring behaviour than a single-mode apparatus, and supports both graphical and numerical methods for spring constant determination.
Product Overview
Springs serve as energy-storing and force-restoring elements across a wide range of engineering applications. Automotive suspension systems rely on compression springs to absorb vertical wheel movement, while spring balances use deflection under load to measure applied forces. Both compression and extension springs operate under the same governing principle — Hooke’s Law — which states that within the limit of proportionality, the deflection of a spring is directly proportional to the applied load.
The FortiTestX 03 is built around a single load application mechanism that serves both spring modes without reconfiguration of the weight system. A compression spring is seated flat against the lower inner surface of the anodized aluminum wall-mounted housing, with industry-standard ground ends ensuring stable and uniform seating. Extension springs hang from an upper adjustable rod connected to a moving plate within the compression mechanism. The profiled boss, with its chamfered face, centers the load on the spring and is designed to accommodate springs of varying outer diameters in both compression and extension configurations.
Compression is measured using a built-in scale and pointer. The compression indicator is adjustable along the load hanger shaft to set the zero reference for springs of different free lengths. For extension springs, the top bracket is repositionable along the upper shaft to adjust the initial height of the spring. Students apply calibrated weights incrementally, record the change in spring length at each load step, plot load versus deflection graphs, and calculate the spring constant. A parallel numerical calculation exercise, using the spring’s measured physical dimensions and the supplied formulae, allows direct comparison with experimental results and manufacturer data.

The FortiTestX 02 Compression of Spring Apparatus is a wall-mounted experimental unit designed to demonstrate Hooke’s Law and determine spring stiffness through direct load application. Manufactured by SCIENTICO, this apparatus is developed for use in strength of materials and mechanics of solids laboratory programmes across engineering colleges, polytechnics, and technical training institutes. It provides students with both experimental and numerical methods for calculating the spring constant, supported by a full set of compression springs, calibrated weights, and a built-in vernier measurement scale.
Product Overview
Springs are fundamental mechanical components used in energy storage, force transmission, and vibration absorption. In automotive suspensions, springs absorb road impact; in spring balances, deflection measurements are used to determine applied loads. Both applications rely on the same foundational principle — Hooke’s Law — which states that within the limit of proportionality, the deflection of a spring is directly proportional to the applied load.
The FortiTestX 02 provides a controlled platform for students to verify this relationship experimentally. A compression spring is seated on the lower inner surface of an anodized aluminum wall-mounting housing. A profiled boss, connected to the load hanger, rests on top of the spring. The chamfered design of this boss centers the load on the spring and accommodates springs of varying diameters. As calibrated weights are added to the load hanger, the spring compresses. A compression indicator mounted on the hanger shaft — aligned with a horizontal reference line — allows the compression value to be read directly from the integral vernier scale.

The SCIENTICO FrixoDynamics FX-529 Pressure Distribution in Journal Bearings Apparatus is a specialised tribology unit for the direct visualisation of the radial pressure profile within a hydrodynamically lubricated journal bearing. Thirteen tube manometers measure the oil pressure at equally distributed points around the bearing shell circumference, displaying the pressure distribution as a set of readable liquid column heights. The bearing gap is adjustable via a micrometer screw from 0 to 2.5 mm, and shaft speed is continuously variable from 0 to 200 rpm via a 200 W geared motor. A fully transparent bearing shell allows direct observation of the lubricating film during operation. Manufactured by SCIENTICO, the FX-529 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
In a hydrodynamically lubricated journal bearing operating under load, the rotating shaft journal displaces the lubricant and generates a pressure distribution within the bearing gap that supports the shaft load without metal-to-metal contact. This pressure distribution is non-uniform around the bearing circumference — pressure builds up on the loaded side of the shaft and drops off on the unloaded side — and its magnitude and shape depend on the shaft speed, the bearing load, the lubricant viscosity, and the bearing gap width. Understanding this pressure distribution is fundamental to journal bearing design, lubrication system specification, and the analysis of bearing stability limits.
The FX-529 makes this pressure distribution directly visible and measurable. The apparatus features a 50 mm diameter stainless steel shaft running in a 52.5 mm internal diameter open bearing shell — a partial enclosure that simulates the journal bearing geometry while allowing pressure measurements to be taken around the full accessible circumference. Thirteen radial pressure measurement ports are distributed around the bearing shell, each connected to an individual glass or transparent tube manometer. As the shaft rotates and generates hydrodynamic pressure in the lubricant film, the oil columns in the manometers rise to heights corresponding to the local pressure at each measurement point, creating a direct visual representation of the circumferential pressure profile.
The bearing shell is mounted on two spring plates that allow it to move in response to the shaft load and hydrodynamic forces — replicating the self-aligning behaviour of a real bearing housing. The gap between the shaft and the bearing shell is adjusted using a radially movable bearing housing controlled by a micrometer screw with a range of 0–25 mm and a graduation of 0.01 mm, allowing the bearing gap to be set precisely between 0 and 2.5 mm. This gap adjustment capability is unique to the experimental setup and allows the effect of gap width on pressure distribution and bearing stability to be investigated systematically.
The 200 W geared motor drives the shaft at speeds continuously adjustable from 0 to 200 rpm, with the current speed shown on the display and control panel. Lubricating oil — 0.5 L supplied — circulates through the bearing gap, and the transparent bearing shell allows the lubricant film to be observed directly throughout the experiment. Students investigate how the pressure distribution changes with speed, bearing gap width, and load, and can identify the stability limit — the gap width below which the bearing transitions from stable hydrodynamic operation toward instability or contact.

The SCIENTICO FrixoDynamics FX-528 Journal Bearing Friction Apparatus is a motorised tribology unit for the experimental investigation of friction phenomena in radial journal bearings under controlled conditions of speed, load, lubrication, and bearing material. A 40 mm diameter stainless steel shaft journal operates within interchangeable bearing shells of sintered bronze, cast iron, and PTFE (Teflon), allowing direct material pairing comparisons under hydrodynamic lubrication. A three-phase AC motor with variable frequency drive (VFD) provides continuously adjustable shaft speed up to 9,999 rpm, with digital display of both speed and lubricant temperature. Friction moment is measured via a lever arm and spring balance system over a range of 30–750 Nmm. Manufactured by SCIENTICO, the FX-528 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Journal bearings — also referred to as plain or sleeve bearings — support radial loads on rotating shafts through a thin film of lubricant that separates the shaft journal from the bearing shell surface. The behaviour of this lubricant film, and the friction it produces, is governed by hydrodynamic lubrication theory. The friction force in a journal bearing is not constant but varies with shaft speed, bearing load, lubricant viscosity, lubricant temperature, and the material pairing at the bearing interface. Understanding these dependencies is a core topic in tribology and machine element design.
The FX-528 provides a systematic experimental approach to all of these variables. The stainless steel shaft journal of 40 mm diameter and 55 mm bearing width operates within a free-moving bearing housing that accepts three interchangeable bearing shells — sintered bronze, cast iron, and PTFE. Each shell is 5 mm thick and conforms to the shaft journal geometry. The free-moving housing design allows the bearing to align naturally with the shaft under load, replicating the self-aligning behaviour of real journal bearings.
Bearing load is applied to the housing using a lever arm and calibrated dead weights, up to a maximum of 200 N. The load is confirmed using a spring balance on the lever. The friction moment generated in the bearing under the applied load and speed conditions is measured via a second spring balance attached to the bearing housing lever at a known arm radius, giving a friction moment reading over the range of 30–750 Nmm. The two spring balances supplied allow both load and friction moment to be measured simultaneously without instrumentation changes between readings.
The three-phase AC motor delivers 750 W (1 hp) and is controlled by a variable frequency drive (VFD) that adjusts the shaft speed continuously from rest to a maximum indicated on the digital display — readable up to 9,999 rpm. An inductive speed sensor provides the speed signal to the digital display, giving a precise, real-time shaft speed readout independent of the VFD frequency setting. Lubricant temperature is monitored continuously by a sensor with a range of −100 to 400°C, displayed digitally alongside the speed, allowing students to observe the effect of temperature rise on lubricant viscosity and friction during extended running.
Lubrication is supplied by a drip-feed lubricator that distributes ISO VG 100 oil (or alternative viscosity grades) to the shaft through a dedicated lubrication channel. Excess lubricant that escapes the bearing is collected in a drip tray, keeping the working area clean and allowing the lubricant consumption rate to be observed. Both the lubricating gap and the shaft journal surface are visible during operation, providing direct visual confirmation of the lubrication condition.

The SCIENTICO FrixoDynamics FX-527 Dry Friction Apparatus is a motorised experimental unit for the systematic investigation of static and dynamic friction between solid bodies under controlled conditions. A synchronous motor drives a carriage at two selectable constant velocities, drawing the support friction surface beneath a stationary friction body connected to a height-adjustable force gauge. Four friction bodies — in two materials and two surface finishes — and multiple interchangeable support surfaces allow the effects of normal force, sliding velocity, material pairing, surface properties, and contact area to be investigated independently. The force gauge is designed to compensate for stick-slip effects, providing a stable mean friction force reading throughout each test. Manufactured by SCIENTICO, the FX-527 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Friction between solid bodies in contact is one of the most practically significant topics in engineering mechanics. Static friction must be sufficient to maintain components in fixed relative positions — as in parking brakes, self-locking threads, and frictional couplings. Dynamic friction must be minimised in relative motion applications such as bearings, guideways, and cutting tools. Understanding the variables that govern friction magnitude — normal force, sliding velocity, material pairing, surface roughness, and contact area — is therefore essential for competent mechanical engineering design.
The FX-527 addresses this need through a clearly structured series of experiments covering each of these variables individually. The apparatus operates on the principle that the friction force on a stationary body is most accurately measured when the contact surface moves beneath it at a constant, controlled velocity — eliminating the dynamic effects of accelerating mass that arise if the friction body itself is pulled. A synchronous motor drives the support friction surface carriage at two fixed velocities — 23.5 cm/min and 47 cm/min — selected via a graduated cable drum. The constant, regulated drive speed ensures that the measured friction force at each velocity is a true steady-state dynamic friction value, not a transient result influenced by acceleration.
The friction body is held stationary and connected to the force measuring unit by a cord. The force measuring unit — a force gauge with a range of 0–10 N and a graduation of 0.05 N — is mounted on a height-adjustable bracket. The height adjustment ensures that the line of action of the friction force at the contact surface and the line of action of the tensile force in the cord to the gauge are parallel at all times, eliminating any moment component that would otherwise introduce error into the force reading. The gauge is also designed to damp stick-slip effects, displaying a stable mean friction force rather than a spiking instantaneous value.
Four friction bodies are provided: smooth aluminium, rough aluminium, smooth brass, and rough brass. The aluminium bodies are 20 mm high and the brass bodies 5 mm high, providing two different contact heights as well as two distinct material pairings. Support friction surfaces of four different surface types are available, allowing any combination of friction body and support surface to be tested. Normal force is varied by adding 0.5 N calibrated weights to the friction body, and the effect of contact area can be investigated by comparing results from different friction body orientations or material pairs.

The SCIENTICO FrixoDynamics FX-525 Equilibrium of Parallel Forces Apparatus is a frame-mounted experimental unit for the verification of equilibrium conditions for sets of parallel coplanar forces acting on a rigid body. Using two acrylic models shaped to simulate Warren and N-type truss structures, and a 12-point circular Perspex disc for couple experiments, students investigate the conditions for vertical force equilibrium, moment equilibrium, and the equilibrium of opposing couples. Force lines are recorded graphically on paper clipped to the force board, enabling direct verification of the link polygon and the conditions ΣFv = 0 and ΣM = 0. Manufactured by SCIENTICO, the FX-525 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
The equilibrium of parallel forces is a foundational topic in statics and structural mechanics. For a rigid body acted upon by a set of parallel coplanar forces to be in equilibrium, two independent conditions must be satisfied simultaneously: the algebraic sum of all vertical forces must equal zero (ΣFv = 0), and the algebraic sum of all moments about any point must equal zero (ΣM = 0). A special case arises when two equal, opposite, and non-collinear parallel forces act on a body, forming a couple — a pure moment with no net resultant force. The equilibrium of opposing couples requires that their moments are equal and opposite.
The FX-525 provides a direct, physically observable and graphically verifiable demonstration of all these conditions. The apparatus is mounted in a Universal Frame and Stand, with a force board as the working surface. Two acrylic models are provided — one shaped and engraved to simulate a Warren truss geometry, and one shaped to simulate an N-type truss. Each model has counterbalancing weights that render the model effectively weightless in the experimental setup, ensuring that only the deliberately applied loads and reactions influence the force system under investigation.
Forces are applied to the acrylic models using nylon cords tensioned by calibrated dead weights on hangers. Double pulleys redirect the cord directions as required, turning upward reaction forces downward so that all forces in the system are applied via hanging weights. The lines of action of all cords are transferred onto a sheet of A1 paper clipped to the force board, providing a permanent graphical record of the force geometry for each experiment. Students then apply the link polygon method to verify ΣM = 0 graphically, and check the algebraic sum of the recorded vertical forces to verify ΣFv = 0.
The circular Perspex disc, fitted with twelve equally spaced peripheral attachment points, is used for the couple equilibrium experiments. Opposing couples are applied at selected attachment points using cords and weights, and students verify that equilibrium requires the two couple moments to be equal and opposite — regardless of the position of the couple arms. The twelve attachment points allow a wide range of couple arm geometries to be tested within a single experiment session.

The SCIENTICO FrixoDynamics FX-524 Dry, Rough and Lubricated Friction Apparatus is a wall or frame-mounted experimental unit for the determination of sliding friction coefficients under three distinct disc surface conditions — dry machined, rough finished, and lubricated — across five different sliding materials and a roller bearing. The apparatus enables students to study how surface condition, material pairing, and braking (normal) force combine to determine the coefficient of friction and the effort required to overcome it. Results are obtained by increasing the effort load on a pulley until the shaft rotates at a steady rate against the applied braking force, and can be presented graphically or as calculated friction coefficients. Manufactured by SCIENTICO, the FX-524 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Friction between contacting surfaces is governed by three principal variables: the nature of the surface finish, the material pairing at the contact interface, and the presence or absence of a lubricant. The FX-524 is designed to isolate and investigate each of these variables systematically, providing a comprehensive practical introduction to tribological principles applicable across mechanical engineering, machine design, and materials science.
The apparatus is built around a main shaft carrying three identically dimensioned discs, each presenting a different surface condition. The first disc has a plain, fine-machined surface representing dry sliding conditions. The second disc is identical in base geometry but incorporates a trough beneath its surface that can be filled with grease or a liquid lubricant, introducing lubricated contact conditions. The third disc has a deliberately rough surface finish, representing a higher-friction dry contact condition. All three discs are mounted on the same shaft, allowing the braking lever to be repositioned over any one of them without changing any other part of the setup.
The braking lever holds interchangeable test samples from five sliding materials — steel, brass, nylon, brake lining, and rubber — as well as a roller bearing. Each sample or the roller bearing is pressed against the selected disc surface by the braking lever, applying a controlled normal (braking) force. The main shaft carries a pulley at one end. An effort hanger is loaded with increasing dead weights until the pulley begins to rotate and the weights descend at a constant rate. At this condition, the driving torque equals the frictional torque at the disc surface, allowing the friction force and the coefficient of friction to be calculated from the known effort load, pulley radius, braking force, and disc geometry.
By conducting the experiment across combinations of disc surface condition, sliding material, and braking force level, students build a dataset that clearly demonstrates how each variable independently and collectively influences the coefficient of friction. The roller bearing test case illustrates the reduction in friction achievable by replacing sliding contact with rolling contact under the same braking force — a direct practical comparison with engineering significance.

Using a set of four friction discs of different geometries and surface materials, students apply a controlled axial load to a clutch plate pressed against a leather disc and measure the torque transmitted at the point of slip. The apparatus supports comparison of different clutch plate geometries — solid disc, clutch lining, loose friction disc, and ring disc — and allows the influence of contact area and surface material on transmitted torque to be studied directly. Manufactured by SCIENTICO, the FX-523 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
A clutch is a mechanical device that connects and disconnects a driven component from a driving component without stopping the prime mover. In a flat disc clutch, torque is transmitted through friction between two axially loaded disc surfaces. The torque capacity of the clutch depends on the coefficient of friction between the contact surfaces, the axial clamping load, and the effective radius of the contact area. When the applied torque exceeds the friction capacity of the clutch, the disc surfaces slip relative to each other, defining the maximum transmittable torque at that clamping load.
The FX-523 demonstrates this operating principle through a directly observable and measurable laboratory setup. A flat leather disc is mounted as the driving surface. The clutch plate — one of four interchangeable friction discs — is pressed against the leather disc face by a loading arm system acting through a thrust bearing, which applies a controlled axial clamping force without transmitting torque to the loading system. The clutch plate is connected to an effort pulley via screws. Two load cords are wound around a pair of 25 mm diameter pulleys, and dead weights are applied to generate torque on the effort pulley. The torque is increased incrementally until the clutch plate slips against the leather disc, establishing the maximum friction torque at that clamping load.
Four friction discs are provided, each of 250 mm outer diameter but with different geometries and surface characteristics: a galvanised steel solid disc, a clutch lining disc, a loose friction disc, and a ring disc with a 150 mm inner diameter. The ring disc eliminates the central contact area, reducing the effective friction radius and contact area relative to the solid discs — allowing students to compare how contact geometry affects the torque capacity for the same clamping load and surface material. Two calculation methods for predicting clutch torque capacity — the uniform pressure theory and the uniform wear theory — can be compared against the experimental results, reinforcing analytical understanding alongside the practical measurements.

The SCIENTICO FrixoDynamics FX-522 Pivot Friction Apparatus is a hand-operated bench-top experimental unit for the investigation of friction in axial bearings — also known as pivot or thrust bearings. The apparatus uses a vertical shaft fitted with interchangeable bearing journals of four different cone angles (60°, 90°, 120°, and 180° flat) and corresponding interchangeable bearing housings of different materials, enabling students to study the effects of cone geometry and material selection on frictional torque. An anodised aluminium disc of 200 mm diameter serves as the load platform and pulley, accepting axial dead weights above and a rope at its periphery for manual torque application. No power supply is required. Manufactured by SCIENTICO, the FX-522 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Axial bearings — or pivot bearings — support loads acting along the shaft axis and are encountered in a wide range of engineering applications including vertical shaft machines, thrust assemblies, and rotary equipment. The friction torque in an axial bearing depends on the axial load, the coefficient of friction between the journal and the bearing housing material, and the geometry of the bearing surface — particularly the cone angle in conical pivot bearings. As the cone angle decreases from 180° (flat disc bearing) toward a sharp point, the contact area geometry changes and the relationship between axial load, contact pressure, and resulting friction torque is modified. The FX-522 allows all of these dependencies to be investigated systematically.
The vertical shaft carries the bearing journal at its lower end. Four interchangeable journal geometries are provided — cone angles of 60°, 90°, 120°, and 180° (flat pivot) — each of which mates with a corresponding bearing housing bolted below the shaft. The bearing housings are available in different materials, enabling the influence of material selection on friction torque to be studied independently of cone geometry. The anodised aluminium disc at the top of the shaft performs two functions: it accepts axial loading weights stacked on its upper surface, increasing the axial load on the bearing journal, and it functions as a pulley from which a rope is hung to apply and measure torque.
Torque is applied manually by pulling the rope wound around the disc periphery, and the load at which the shaft begins to rotate corresponds to the frictional torque of the bearing at the current axial load, cone angle, and material pairing. By systematically varying the axial load using the provided weight sets — including two additional 5 kg loading weights — and repeating the measurement for each cone angle and bearing material, students generate a comprehensive dataset covering the key variables governing axial bearing friction. A comparison experiment using a rolling contact bearing in place of the plain pivot journal demonstrates the reduction in friction torque achievable with rolling element bearings under the same axial load.

The SCIENTICO FrixoDynamics FX-521 Bearing Friction Apparatus is a wall-mounted experimental unit for the determination and comparison of friction torque in sliding and rolling bearing systems. A heavy galvanised steel flywheel is mounted on a stainless steel shaft supported in interchangeable bearing housings, allowing three different sliding bearing shell materials — gun metal, cast iron, and PTFE — to be tested individually and compared against a grooved ball bearing (Type 6203). Torque is applied via a cable drum and dead weight system, and the weight at which motion begins corresponds directly to the frictional torque of the bearing under the flywheel’s dead load. When fitted with rolling bearings, the flywheel’s low-friction rotation also supports fundamental experiments in rotational dynamics. Manufactured by SCIENTICO, the FX-521 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Bearing selection is a fundamental decision in mechanical engineering design. Sliding bearings — also called plain bearings — operate through direct surface contact between the shaft journal and the bearing shell, with friction governed by the material pairing and lubrication condition. Rolling bearings reduce friction by replacing sliding contact with rolling contact between the shaft, rolling elements, and the outer race. The FX-521 enables students to measure the friction torque in both bearing types under identical loading conditions, providing a direct, quantitative basis for comparing their performance.
The apparatus is centred on a 300 mm diameter galvanised steel flywheel of 22.2 kg, mounted on a stainless steel shaft with a 17 mm diameter journal. The shaft is supported in a bearing housing attached to the wall bracket on an anodised aluminium base plate. Three sets of sliding bearing shells are provided — gun metal, cast iron, and PTFE — each set consisting of two shells that form the complete plain bearing around the shaft journal. A Type 6203 grooved ball bearing can replace the plain bearing housing, converting the apparatus to a rolling bearing configuration.
The flywheel’s own dead weight provides the bearing load — the normal force acting on the bearing surface — without requiring any additional loading mechanism. Torque is applied to the flywheel by a cable wound around a cable drum on the shaft, with dead weights suspended from a hanger on the cable. Weights are added incrementally until the flywheel just begins to rotate. The total hanging weight at this point, multiplied by the cable drum radius, gives the frictional torque of the bearing at that load and material combination.
By repeating the measurement for each of the three sliding bearing materials and for the rolling bearing, students generate a direct comparison of friction torque across four bearing configurations. The PTFE shell typically produces the lowest friction among the plain bearing materials, while the rolling bearing will show substantially lower torque than any of the plain bearing configurations — clearly demonstrating the practical advantage of rolling bearings in low-friction applications. With rolling bearings installed, the flywheel’s smooth, low-resistance rotation can additionally be used for introductory experiments in rotational dynamics, including investigations of moment of inertia and angular deceleration.

The SCIENTICO FrixoDynamics FX-530 Cord Friction Apparatus is a wall-mounted experimental unit for the investigation of friction between a cotton rope and steel pulleys of four different groove profiles — flat rim, 120°, 90°, and 60° V-groove angles. Students determine the coefficient of friction between rope and pulley, investigate the relationship between the tight-side and slack-side belt tensions across a range of lap angles, and compare how the V-groove angle affects the effective friction and tension ratio. The lap angle is varied by using alternative mounting positions for the interchangeable second pulley. A complete loop of cotton rope, two load hangers, and a calibrated weight set are included. Manufactured by SCIENTICO, the FX-530 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
When a rope or belt passes over a pulley, the ratio of the tensions on the two sides is governed by the rope friction equation — an exponential relationship involving the coefficient of friction and the angle of lap (contact angle). For a rope seated in a V-groove pulley, the effective coefficient of friction is amplified relative to a flat rim pulley because the groove flanks generate a wedging action, increasing the normal force on the rope for the same applied tension. This makes V-groove pulleys significantly more effective at transmitting force without slip, and the degree of this amplification depends directly on the groove angle.
The FX-530 allows students to investigate both of these phenomena — the effect of lap angle on the tension ratio, and the effect of V-groove angle on the effective friction — through systematic, controlled experiments. The apparatus is wall-mounted and consists of a fixed pulley and a second interchangeable pulley. A continuous loop of cotton rope passes over both pulleys with two load hangers at its lower ends. One hanger carries a base load to tension the rope; the other hanger carries an increasing load until the rope just begins to slide over the pulley under test. This identifies the critical tension ratio at the onset of slip, from which the coefficient of friction is calculated.
The lap angle is changed by moving the interchangeable pulley to alternative mounting positions on the wall bracket, altering the geometry of the rope path between the two pulleys. Each of the four pulleys — flat rim, 120°, 90°, and 60° — can be mounted in place of the interchangeable pulley, allowing the effect of groove angle to be investigated independently of the lap angle. By conducting the experiment across combinations of groove angle and lap angle, students build a comprehensive dataset that verifies the rope friction equation and clearly demonstrates the wedging effect of V-groove profiles.

The SCIENTICO FrixoDynamics FX-520 Drum Friction Apparatus is a bench-top experimental unit for the investigation of friction in a drum brake system using a single pivoted brake shoe. Students determine the relationship between the braking load applied to the shoe and the tangential force generated at the drum surface, derive the coefficient of friction between the aluminium drum and the brake shoe material, and compare the behaviour of the brake shoe as a leading shoe and as a trailing shoe by reversing the direction of drum rotation. The apparatus directly simulates the operating principle of a real drum brake system and uses calibrated dead weights applied via cord and hanger to control both drum torque and braking load. Manufactured by SCIENTICO, the FX-521 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Drum brakes are widely used in automotive and industrial applications. Their performance depends critically on the coefficient of friction between the brake shoe lining and the drum surface, and on whether the shoe is configured as a leading shoe or a trailing shoe relative to the direction of drum rotation. A leading shoe is one whose pivot geometry causes the friction force to draw the shoe tighter against the drum as braking load increases — producing a self-energising or servo effect that amplifies the braking force beyond the directly applied load. A trailing shoe exhibits the opposite behaviour, with friction tending to push the shoe away from the drum, requiring higher applied loads to achieve the same braking torque. The FX-520 allows both behaviours to be demonstrated and compared within the same apparatus simply by reversing the direction of drum rotation.
The apparatus consists of a plain aluminium drum of 130 mm internal diameter, machined to a precise surface finish. A cord is wound around the drum perimeter and connected to a torque hanger. By adding calibrated weights to this hanger, a known torque is applied to the drum, tending to rotate it. Inside the drum, a single brake shoe is mounted on a pivot and connected via a separate cord to a braking load hanger. As weights are added to the braking load hanger, the shoe is pressed against the inner drum surface, generating a friction force that opposes drum rotation. The student adds weights to the torque hanger until the drum rotates at near-constant speed, establishing the relationship between the torque-producing tangential force and the applied braking load at that condition.
By recording the torque hanger load and the braking load hanger load at successive braking load increments, students construct a tangential force versus braking load graph. The slope of this graph gives the coefficient of friction directly. Repeating the experiment with the drum torque cord rewound in the opposite direction reverses the sense of rotation, converting the leading shoe configuration to a trailing shoe configuration, allowing the characteristic difference in braking behaviour between the two to be clearly observed and quantified.

The SCIENTICO FrixoDynamics FX-519 Belt and Cord Friction Apparatus is a portable, bench-mounted experimental unit for the determination of friction coefficients in belt and cord systems, and for the verification of Eytelwein’s rope friction formula across three belt types — flat belt, V-belt, and round belt. The apparatus uses a 150 mm diameter cast iron pulley with three distinct belt grooves, and allows the angle of contact to be adjusted between 30° and 210° in 30° increments. Two calibrated weight sets apply the belt tensions required for the experiment, and the influence of contact angle, belt type, and tension ratio on frictional behaviour can be investigated systematically. Manufactured by SCIENTICO, the FX-519 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Friction in belt drives governs both the power transmission capability and the wear characteristics of the belt and pulley system. The relationship between the tight-side tension, the slack-side tension, the angle of contact, and the coefficient of friction is described by Eytelwein’s rope friction formula — also known as the belt friction equation. This states that the ratio of the tensions on the two sides of a belt wrapped around a pulley is an exponential function of the product of the friction coefficient and the angle of contact. The FX-519 is designed to allow students to verify this relationship experimentally for three different belt profiles and to compare the frictional behaviour of each.
The apparatus consists of a ball bearing-mounted pulley of 150 mm diameter, manufactured from anodised cast iron, fitted with three grooves corresponding to the flat belt, V-belt, and round belt profiles. The pulley is mounted on a rigid metal stand frame. A belt is passed over the pulley at a selected contact angle, which is set and read from a graduated scale on the frame at 30° increments from 30° to 210°. One end of the belt carries a load hanger to which weights are applied, representing the load-side tension. The pulley is then rotated against this load by pulling on a cord attached to a second hanger on the opposite side, with weights added until the belt begins to slip or reaches equilibrium — establishing the tight-side tension.
By recording both tension values at each contact angle and for each belt type, students apply the Eytelwein formula to calculate the implied coefficient of friction, and compare the results across flat belt, V-belt, and round belt configurations. The influence of incorrectly aligned belts on friction and slip behaviour can also be demonstrated, connecting the laboratory experiment directly to practical belt drive maintenance and design considerations.

The SCIENTICO FrixoDynamics FX-518 Coriolis Force Apparatus is a motorised, bench-top demonstration and experimental unit for the direct visualisation of the Coriolis effect — the apparent deflection experienced by a body moving in a straight path within a rotating reference frame. The apparatus uses a submersible pump to project a radial water jet from a transparent tank mounted on a rotating arm. The deflection of the water jet relative to its stationary-arm trajectory is observed on a graduated scale and varies with the speed and direction of arm rotation. A digital speed sensor displays the arm rotation rate throughout the experiment. Manufactured by SCIENTICO, the FX-518 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
The Coriolis effect arises when the motion of a body is observed from within a rotating reference frame. An object moving in a straight line relative to an inertial (non-rotating) frame appears to follow a curved path when viewed from the rotating frame. The magnitude of the apparent deflecting force — the Coriolis force — is proportional to the speed of the rotating frame and the velocity of the moving object within it. This effect governs large-scale atmospheric and oceanic circulation patterns and is a fundamental concept in dynamics, fluid mechanics, and geophysics.
The FX-518 makes this otherwise abstract phenomenon directly visible at laboratory scale. The rotating arm assembly sits on top of the main base unit and is driven at an infinitely adjustable speed between 0 and 60 rpm. Mounted on the arm is a transparent water tank fitted with a submersible pump capable of a maximum flow rate of 2 L/min. The pump delivers water through a single nozzle, projecting a radial water jet outward from the pivot point of the arm.
When the arm is stationary, the jet travels in a straight radial line, establishing the reference trajectory. When the arm rotates, the jet is deflected from this straight-line path due to the Coriolis effect. The direction of deflection reverses with the direction of arm rotation, and the magnitude of deflection increases with rotation speed — both directly observable on the graduated scale marked on the water tank. The closed water circuit recirculates water from the tank through the pump and back, allowing continuous operation without the need for an external water supply.
A speed sensor monitors the arm rotation rate and displays it digitally on the control panel, enabling systematic correlation between rotation speed and the degree of water jet deflection observed. Students can compare the deflected jet trajectory at different speeds against the stationary reference path, developing a quantitative appreciation of how Coriolis force magnitude scales with angular velocity.

The SCIENTICO FrixoDynamics FX-517 Work Done by Variable Force Apparatus is a bench-top experimental unit designed to give students a practical, measurable demonstration of the concept that mechanical work done by a variable force equals the area under the force-distance graph. The apparatus supports two distinct experiment modes — a vertical force mode using a suspended trolley and pulley system, and a tangential force mode using a pivoted arm restrained by a spring balance — each producing a nonlinear force-distance relationship that must be integrated graphically to determine the work done. A 0–100 N spring balance, integrated protractor scale, and ball bearing-mounted pulleys are included as standard. Manufactured by SCIENTICO, the FX-517 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
Work done by a constant force is straightforwardly calculated as the product of force and displacement. However, when the force varies with position — as is common in real mechanical systems — the work done must be determined by integrating the force over the displacement, which is geometrically equivalent to finding the area under the force-distance curve. The FX-517 demonstrates this principle through two physically distinct experiment configurations that each exhibit clear, measurable nonlinearity.
In the vertical force experiment, a suspension cord carries a loaded trolley at its midspan. The cord passes over a ball bearing-mounted pulley at one end and down to a weight hanger. As the vertical effort load is increased incrementally, the cord moves to a new equilibrium position, lifting the trolley. The height of both the effort hanger and the trolley load are recorded at each increment relative to the base. The resulting effort-versus-displacement graph is nonlinear, and the area under it — determined graphically or numerically — gives the work done in lifting the trolley. This is compared against the change in potential energy of the trolley, providing a direct energy balance verification.
In the tangential force experiment, a pivoted arm carries a load hanger at its free end. A spring balance is attached perpendicular to the arm and restrains it at a defined angular position indicated by the protractor scale on the backboard. The force in the spring balance represents the effort required to hold the weighted arm at that angle. By repeating the measurement at a series of angular positions — and for different applied weights — students obtain a force-versus-angle dataset from which a force-distance curve is constructed. The area under this curve gives the work done in moving the arm through the angular range.
Both experiment modes clearly establish that the force is not constant and that simple force-times-distance multiplication would give an incorrect result, reinforcing why graphical integration is the correct approach for variable force systems.

The SCIENTICO FrixoDynamics FX-516 Polygon of Forces Apparatus is a self-contained, bench-mounted unit for the experimental investigation of equilibrium conditions for coplanar force systems. Up to five independently adjustable loads are applied to a circular disc via pulleys mounted at variable angular positions around its perimeter, and the conditions for equilibrium are established by centralising a small ring over the central pin using weighted cords. The lines of force action are recorded graphically by tracing the weighted cords onto paper attached to the disc surface, allowing direct construction and verification of the triangle of forces, polygon of forces, and link polygon. Manufactured by SCIENTICO, the FX-516 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
The equilibrium of coplanar forces is a foundational topic in statics. A system of coplanar forces is in equilibrium when both the vector sum of all forces and the sum of all moments about any point are zero. The FX-516 provides a direct, physically intuitive demonstration of this principle for both concurrent and non-concurrent force systems, using calibrated dead weights and a rotatable pulley system to establish and vary the force configuration.
The apparatus is built around a horizontal circular disc mounted on three legs above a stable base. A 360° protractor is printed on the disc surface, providing a direct angular reference for each force direction. Up to five pulleys are clamped at chosen positions around the disc perimeter, with each pulley redirecting a weighted cord from the central ring outward over the disc edge and downward to a load hanger. The forces acting on the central ring are therefore defined by the hanging weights and the angular positions of the pulleys.
Equilibrium is achieved when the central ring, pulled by all the concurrent cords, centres itself over the central pin without contacting it. The weighted cords are then traced onto a sheet of paper placed on the disc, recording the exact lines of force action. These lines, together with the known load magnitudes, are used to construct a polygon of forces graphically — closing the polygon confirms equilibrium and verifies the experimental result against the graphical method.
For non-concurrent force systems, the loads are applied at different points around the disc or on a rectangular lamina shape, and the link polygon method is used for graphical verification. The combination of physical force balance and graphical polygon construction gives students a comprehensive understanding of both the analytical and geometric approaches to force equilibrium.

The SCIENTICO FrixoDynamics FX-515 Two Arm Lever Apparatus is a bench-top experimental unit for the study of moment equilibrium on a centrally pivoted beam. Students apply loads at varying distances from the central pivot on both arms of the lever and investigate the conditions required to achieve rotational equilibrium, directly verifying the law of moments. The beam is centrally mounted on precision ball bearings, and its integrated scale allows lever arm lengths to be read directly without additional measuring instruments. Three sets of weights and three riders with hooks provide a wide range of load and position combinations. Manufactured by SCIENTICO, the FX-515 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
The law of moments states that a body is in rotational equilibrium when the sum of clockwise moments about a pivot equals the sum of anticlockwise moments. The FX-515 demonstrates this principle through direct physical experimentation on a two-arm lever — one of the most fundamental mechanical systems in statics and applied mechanics.
The apparatus consists of a 600 mm beam centrally mounted on a sturdy vertical metal frame via a ball bearing pivot. With 300 mm of lever arm available on each side of the pivot, students position riders with hooks at chosen points along the beam scale and hang known weights from them. The moment generated by each load is the product of the weight and its distance from the pivot. By adjusting the positions and magnitudes of loads on both arms, students find the combinations that produce equilibrium — confirming the moment balance condition experimentally.
The ball bearing mounting ensures that the pivot introduces negligible friction, so the beam responds sensitively to small moment imbalances. This makes the FX-515 suitable for precise, quantitative experiments rather than purely qualitative demonstrations. Three riders allow up to three simultaneous load positions to be set on the beam, enabling experiments involving multiple forces on one or both arms — progressively increasing in complexity as students gain confidence with the fundamental principle.

The SCIENTICO FrixoDynamics FX-514 Forces in Truss Apparatus is a fully instrumented structural mechanics unit for the experimental measurement of bar forces in single-plane statically determinate trusses. Bars of six different lengths are connected via pin-jointed node discs, allowing three distinct truss configurations to be assembled within a rigid support frame. Each bar is fitted with a strain gauge load cell, and all force data is acquired simultaneously through a 12-channel measurement amplifier and processed using dedicated DAQ software developed in the National Instruments LabVIEW environment. Results can be compared directly against theoretical values obtained by the method of joints and Ritter’s method of sections. Manufactured by SCIENTICO, the FX-514 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
A truss is a structural form in which individual straight members — connected only at their ends through pin joints — carry load exclusively as axial tension or compression. Because no moments are transmitted at the nodes, the force in each bar can be determined analytically using equilibrium equations alone, making trusses one of the most tractable structural systems in undergraduate structural analysis. The FX-514 brings this analytical framework into the laboratory, allowing students to physically construct a truss, apply a controlled external force, measure the resulting bar forces instrumentally, and compare those measurements against two established theoretical methods.
The apparatus is assembled in a rigid metallic frame that provides fixed support locations for the truss. Bars are available in six lengths — 150 mm, 259 mm, 300 mm, 397 mm, 424 mm, and 520 mm — and are joined at node discs using pin-install closures that engage quickly and securely without tools. The angular relationships between connected bars — at 30°, 45°, 60°, and 90° — are determined by the choice of bar lengths and node disc positions, with three distinct truss geometries constructible from the standard bar set.
An external force is applied to a selected node disc using the load application device, which incorporates a force gauge with a range of −500 to +500 N and a graduation of 0.01 N. The direction and point of application of this force can be changed by repositioning the device on different node discs, allowing students to investigate how both the magnitude and point of application of the external load affect the distribution of bar forces throughout the truss.
Each bar carries its own strain gauge load cell. All 12 input channels feed simultaneously into the measurement amplifier, and the LabVIEW-based DAQ software acquires, processes, and graphically displays the bar forces in real time. The software supports direct export and comparison of measured values against theoretical calculations, and includes a comprehensive help function. All components are housed in a dedicated storage system and the complete experimental setup is arranged within the frame for clear, orderly use.

The SCIENTICO FrixoDynamics FX-513 Fundamentals of Statics Apparatus is a modular, panel-based experimental unit covering the core principles of statics including force resolution, equilibrium, the law of levers, moment determination, and pulley systems. The upright panel accepts a wide range of interchangeable mountings — cables, rods, pulleys, pivot bearings, and torque discs — that can be attached rapidly to the aluminium rail system around the panel edges and reconfigured between experiments. An imprinted 50 mm line grid, writeable surface, and integrated ball bearings for low-friction torque experiments make the FX-513 one of the most versatile and instructionally complete statics units available for undergraduate laboratory use. Three optional supplementary sets extend the scope to friction on an inclined plane, pulley blocks, and gear wheels. Manufactured by SCIENTICO, the FX-513 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
The FX-513 is built around a 600 x 700 mm upright panel set in portrait orientation and stabilised on a laboratory bench by feet at its base. The panel surface is imprinted with a 50 mm line grid that serves as a direct geometric reference for angle identification, force vector construction, and measurement of lever arm lengths — eliminating the need for separate rulers or protractors during most experiments. The grid also allows force parallelograms and resolution diagrams to be drawn directly on the panel using erasable markers, combining physical experiment with graphical analysis in a single workspace.
Aluminium rails run along the edges of the panel, providing a universal mounting track for the full range of experiment components. Lever rods of 600 mm and 400 mm length, each marked with a 50 mm grid, can be mounted horizontally or at any angle. Pulleys, pivot bearings, torque discs, cables, and rods are attached and repositioned quickly without tools, allowing the experimental configuration to be changed in minutes. Two spring balances and two weight sets provide the force measurement and loading capability for the standard experiment range.
Ball bearings are integrated into the panel at the pivot mounting points, ensuring low-friction rotation for torque and moment experiments. This reduces systematic error in lever and moment of force experiments, producing results that more closely match theoretical predictions. The writeable panel surface allows instructors to annotate experiments in progress and students to record observations, vector diagrams, and calculations directly alongside the physical setup.
The standard unit covers force parallelogram and composition, force resolution, equilibrium of concurrent forces, law of levers, moment determination, equilibrium of moments, and fixed and free pulley systems. Three optional supplementary sets — inclined plane and friction, pulley blocks, and gear wheels — extend the experimental programme further, making the FX-513 a long-term platform for progressive laboratory courses.

The SCIENTICO FrixoDynamics FX-512 Forces in Simple Bar Structure Apparatus is a bench-top experimental unit for the measurement and analysis of internal forces in a statically determinate, single-plane pin-jointed truss. The apparatus replicates a simple roof truss configuration using three metallic bars connected at node discs, with each bar fitted with an individual force gauge for direct measurement of compressive and tensile forces. The adjustable base member allows the truss geometry to be reconfigured across several angle combinations, and the method of joints provides the analytical framework for comparing calculated bar forces against measured values. Manufactured by SCIENTICO, the FX-512 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
A simple bar structure — or pin-jointed truss — is a structural system in which straight members are connected at their ends through frictionless pin joints called nodes. Because loads are applied only at the nodes, and the joints are free to rotate, each bar member carries only axial force — either compression or tension — with no bending. This makes the truss one of the most analytically tractable structural systems and a fundamental topic in structural mechanics and statics courses.
The FX-512 represents this system physically using three bars arranged in a triangular configuration. Two of the bars are rafters of fixed length (440 mm each), carrying compressive forces under downward loading, and fitted with compression force gauges. The third bar is the tie — the base member — which is longitudinally adjustable to lengths of 440 mm, 622 mm, or 762 mm, altering the geometry of the truss and carrying tensile force under load. Each bar connects to its neighbours through node discs secured by quick-lock mechanisms, allowing rapid reconfiguration without tools.
Two of the three node points serve as support conditions — one fixed and one free to move longitudinally on bearings — replicating the standard simply supported truss boundary conditions used in analytical calculations. The third node, at the apex, carries the external load applied through a weight hanger. Force gauges at the midpoint of each bar display the internal bar force directly, with a measuring range of 0–100 N and a graduation of 0.5 N.
Students apply the method of joints — formulating equilibrium equations at each node — to calculate the theoretical bar forces and compare these against the gauge readings. The graphical force polygon method can also be applied and compared, giving students three parallel routes to the same result: experimental measurement, analytical calculation, and graphical construction.

The SCIENTICO FrixoDynamics FX-511 Toggle Joint Apparatus is a bench-top experimental unit for the study of force distribution and reaction forces in a loaded toggle joint mechanism. The apparatus demonstrates how the horizontal reaction force at the moveable end of the base member varies as a function of the joint angle, using straightforward force resolution principles. A mechanical spring balance measures the horizontal force directly, and a set of dead weights allows the applied load to be varied in defined steps. The opening angle is continuously adjustable between 30° and 135°, and the entire unit is of robust, solid metal construction. Manufactured by SCIENTICO, the FX-511 is suitable for supply to engineering institutions and distributors worldwide.
Product Overview
A toggle joint is a three-member mechanism arranged in a triangular configuration. Two members are of fixed length, while the third — the base member — is variable in length, extending or contracting under the horizontal reaction force generated when a vertical load is applied at the apex of the triangle. The key characteristic of a toggle joint is the relationship between the applied vertical load and the resulting horizontal reaction force, which varies significantly with the angle of the joint. As the joint angle approaches 180° (fully extended), a relatively small vertical load produces a very large horizontal force — a principle exploited in mechanical presses, clamping devices, and linkage mechanisms.
The FX-511 allows students to investigate this relationship experimentally. The triangular assembly is mounted on a rigid metallic base, with one end of the base member fixed and the other end free to move horizontally. A weight hanger at the apex of the triangle accepts dead weights, applying a known vertical load to the joint. The horizontal reaction force transmitted to the moveable end of the base member is measured by a mechanical spring balance with a range of 0–10 kg and a graduation of 50 g.
The joint angle is set using a continuously adjustable device, allowing the opening angle to be varied between 30° and 135°. At each angle setting, the applied load can be varied using the provided weight set, and the corresponding spring balance reading is recorded. Students then resolve forces analytically at the apex to calculate theoretical horizontal reaction forces and compare these against the measured values, developing a quantitative understanding of how joint geometry governs force amplification in toggle mechanisms.
