The experimental wall mounting setup demonstrates the relationship between tensile loading and elastic wire elongation. It enables inferences to be drawn about the physical properties. On a carrier fixed on the wall, wire specimens are hanged. Two sliders are used to attach the bottom ends. A traverse connects the wires and makes it possible to apply an even load. The traverse supports a set of weights for loading the wires. The moment lever, which has a dial gauge, can be used to measure the elongation of the wires as a result of the tensile tension
