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