The Young's Modulus Apparatus FortiTestX-43 is a wall-mounted laboratory unit for investigating elastic elongation of metal wire specimens under direct tensile loading. This Young's modulus apparatus supports experiments with steel, aluminium, brass, and copper wires (1000 mm length, 1 to 2 mm diameter), measuring elongation via a vernier gauge with a 100 mm range and 0.02 mm graduation. A traverse distributes load evenly from the weight set to the wire bottom ends, enabling systematic study of elongation as a function of load, diameter, and material. The unit supports direct determination and verification of the modulus of elasticity for all four wire materials.

Construction and Design
The Young's Modulus Apparatus FortiTestX-43 is mounted on a wall-fixed carrier from which wire specimens in steel, aluminium, brass, and copper are suspended vertically. Each wire is 1000 mm long with a diameter between 1 and 2 mm. The bottom ends of the wires are attached using two sliders that connect to a traverse. The traverse distributes the applied load evenly across the wire specimens and supports the weight set for direct tensile loading. A moment lever fitted with a vernier gauge measures elongation of the wires under load, with a displacement range of 100 mm and graduation of 0.02 mm. This Young's modulus apparatus allows the effect of load magnitude, wire diameter, and material on elastic elongation to be systematically investigated, and enables direct calculation and verification of the modulus of elasticity from the measured data.
Scope of Delivery
Scope of delivery not specified in source data. Please confirm with SCIENTICO before publishing.
Q1: What wire materials are included with the Young's Modulus Apparatus FortiTestX-43?
Four wire materials are provided: steel, aluminium, brass, and copper, each 1000 mm in length with a diameter between 1 and 2 mm.
Q2: How is wire elongation measured on this Young's modulus apparatus?
Elongation is measured using a vernier gauge mounted on a moment lever. The measuring range is 100 mm with a graduation of 0.02 mm.
Q3: How are loads applied to the wire specimens?
Weights are placed on a traverse that connects the bottom ends of the wire specimens, applying a direct and evenly distributed tensile load.
Q4: What variables can be investigated with the FortiTestX-43?
Elastic elongation can be investigated as a function of applied load, wire diameter, and wire material. The modulus of elasticity can also be determined and verified experimentally for each material.
Q5: What weight values are included with the apparatus?
The unit includes 1x 1 N hanger weight, 1x 1 kg weight, and 4x 2 kg weights.
