This jig is used to determine the Young's modulus of a wire by the method of G.F.C. Searle described in Worsnop and Flint, 'Advanced Practical Physics for Students'. The stretching of a wire sample hanging from the ceiling under increasing load is monitored by comparison with a second wire with a constant load. This is done using a micrometer screw attachment to return a bubble level to centre. (the screw dial is missing here). It is one of six units listed in the Equipment Register book.
