A tensile load of 50.000 lb is applied to a metal bar with a 0.6 in. × 0.6 in. cross section and a gage length of 2 in. Under this load the bar elastically deforms so that the gage length increases to 2.007 in. and the cross section decreases to 0.599 in. × 0.599 in. Determine the modulus of elasticity and Poisson’s ratio for this metal.
