SUMMARY
The experiment set-up for measuring Young's modulus involves suspending two wires from the same rigid support to minimize errors related to the yielding of the support under load. Both wires are made of the same material to ensure consistency in thermal expansion and mechanical properties. One wire serves as a reference to reduce temperature-related errors, while the extension of the test wire is accurately measured using a vernier scale. This standard approach enhances the reliability of the Young's modulus measurement.
