A 14-in.-long steel rod, . in diameter, was subjected to an axial tensile load of 60,000 lb in a universal testing machine. It was observed that a gage length of 2 in. near the midpoint of the rod increased in length by 0.0023 in. and the rod diameter decreased by 0.00043 in. Assume the steel proportional limit to be 34,000 psi. Calculate the modulus of elasticity and Poisson’s ratio for the steel.
