Question details

Poissons Ratio v is a material property and is the ratio of lateral strain and the longitudinal strain for member in tension. For a homogeneous, isotropic material, and modulus of rigidity G is related to Youngs modulus as 1. Using the tabulated values of G and E in Table A-5, compute Poissons ratio for Inconel, Douglas Fir, and Carbon Steel. Determine the percent difference between the computed values and the values tabulated in Table A-5
