a tensile load of 50000 lb is applied to a metal bar with a 0.6 inch by 0.6 inch cross section and a gage length of 2 inch . under this load the bar elastically deforms so that the gage length increases to 2.007 inch and the cross section decreases to 0.599 by 0.599 in. Determine the modulus of elasticity and possoins ratio for this metal
