A tensile load of 50 000 lb is applied to a metal bar with a 0.6x0.6 in cross section and a gage length of 2 in. Under this load the bar elastically deforms so that the gae length increases to 2.007 in. and the cross section decreases to 0.599x0.599 in. Determine the modulus of elasticity and the poisson's ratio for this metal.
