Key Features
Key Features
- Single wall-mounted unit capable of testing both compression and extension springs
- Common load hanger and weight set used for both spring modes, no separate loading hardware required
- Profiled boss with chamfered face self-centers the load and accommodates a range of spring outer diameters
- Adjustable compression indicator allows zeroing for springs of varying free lengths
- Repositionable upper bracket enables adjustment of the initial extension spring height
- Supplied with 6 compression springs and 6 extension springs covering multiple diameter and wire diameter combinations
- Built-in scale with pointer for direct deflection measurement
- Comprehensive experimental manual with reference data and spring constant calculation formulae
Applications
- Experimental verification of Hooke's Law under both compressive and tensile loading
- Determination of spring stiffness using load-deflection graphs
- Numerical calculation of spring constant from measured spring dimensions
- Comparative study of how wire diameter, coil diameter, free length, number of turns, and material affect spring stiffness
- Plotting and analysis of load versus compression and load versus extension graphs
- Side-by-side comparison of compression and extension spring behaviour under equivalent loads
- Comparison of experimental results with theoretical estimates and manufacturer-supplied spring data
Construction and System Design
The housing is fabricated from anodized aluminum, providing a rigid and corrosion-resistant wall-mounting frame. The lower seating surface is flat and horizontal to ensure stable compression spring placement with ground ends. The profiled boss is precision-machined with a chamfered face for consistent axial loading across springs of different outer diameters, and is designed to function in both the compression and extension loading configurations. The extension spring upper bracket is mounted on a vertically adjustable shaft, allowing the unit to accommodate springs of different free lengths without hardware changes. The load hanger incorporates a solid base for safe and stable suspension of the calibrated weight set. The built-in measurement scale and adjustable pointer provide direct, readable deflection values for both spring types.

Frequently Asked Questions
1. What is the difference between the FortiTestX 02 and the FortiTestX 03?
The FortiTestX 02 is a dedicated compression spring testing unit, while the FortiTestX 03 is a combined apparatus capable of testing both compression and extension springs using a single load hanger and weight set. The FortiTestX 03 is better suited for courses that require the study of both spring types within the same laboratory session.
2. How are extension springs tested on the FortiTestX 03?
Extension springs hang from an upper adjustable rod connected to the moving plate of the compression mechanism. The top bracket is repositioned along the upper shaft to set the correct initial spring height. The same calibrated weights and load hanger used for compression testing apply the tensile load to the extension spring.
3.How many springs are supplied with the FortiTestX 03?
The apparatus is supplied with 6 helical compression springs with outer diameters from 24 mm to 46 mm and wire diameters ranging from 1.5 mm to 2.5 mm, along with 6 extension springs in two outer diameter groups, 15 mm and 20 mm, each available in 3 wire diameters.
4.Can the same weight set be used for both compression and extension experiments?
Yes. The FortiTestX 03 uses a single common load hanger and calibrated weight set, comprising 1 x 1 N hanger, 2 x 1 N, 4 x 2 N, and 6 x 5 N weights, for both compression and extension loading. No separate loading hardware is required for switching between the two modes.
5.What experiments can be conducted with the FortiTestX 03?
The apparatus supports verification of Hooke's Law for both spring types, determination of spring stiffness by graphical and numerical methods, comparative study of the effect of wire diameter, coil diameter, free length, and number of turns on stiffness, and comparison of experimental results with theoretical and manufacturer data.
