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 (225 lbf) produces an elastic reduction in diameter of 2.8 × 10−4 mm (1.10 × 10−5 in.). Compute the elastic modulus for this alloy, given that Poisson's ratio is 0.30.
