Title1R20.15-1 - Young's Modulus - Stretching of a Copper wire - Horizontally
Objective

​To demonstrate how much a copper wire will stretch when a force is applied as it is related to the Young's modulus.

StatusAvailable
Assembly Instructions

​Hook a copper wire around a bench rod.  Connect to that a hook with attached string to hang the masses from.  Run the string over a pulley assembly that has a position indicator on it.  As the mass is applied, the position indicator will rotate.  Given the radius of the pulley and the angular displacement to determine the amount of stretching that occurs.
