A Cylindrical Specimen Of Some Alloy 8 Mm 031 In

A cylindrical specimen of some alloy 8 mm (0.31 in.) in diameter is stressed elastically in tension. A force of 15,700 N (3530 lbf) produces a reduction in specimen diameter of 5 ( 10-3 mm (2 ( 10-4 in.). Compute Poisson’s ratio for this material if its modulus of elasticity is 140GPa (20.3 ( 106psi).
