# Question: Poissons ratio is a material property and is the ratio

Poisson’s ratio ν is a material property and is the ratio of the lateral strain and the longitudinal strain for a member in tension. For a homogeneous, isotropic material, the modulus of rigidity G is related to Young’s modulus as

G = E/2(1 + v)

Using the tabulated values of G and E, determine Poisson

G = E/2(1 + v)

Using the tabulated values of G and E, determine Poisson
