Experimentally, how would you calculate the Young's modulus of a material?
Young's modulus = stress/strain. Stress = F/A Strain= e/l. Measure the length of a wire between 2 points, placing a marker at each. Also measure the diameter to calculate the cross sectional area of the wire. Apply a set load and measure the increase in length. Then use the previously stated equations to calculate the Young's modulus.
