Consider a cylindrical specimen of some hypothetical metal alloy that has a diameter of 8.0 mm (0.31 in.). A tensile force of 1000 N (225lb_f) produces an elastic reduction in diameter of 2.8 × 10^-4 mm (1.10 × 10^-5 in.). Compute the modulus of elasticity for this alloy, given that Poisson's ratio is 0.30.
