Question

Example 13.15 Calculate the Poisson's ratio for silver. Given Young's modulus for silver it 7.25 x1010 N/m2 and bulk modulus is 11 x 1010 N/m². (Meerut. U., 2001) Solution Y=725 X1010 N/m2 V 11 10...2​

Answer 1

Given: Y= 7.25 x1010 N/m2, K= 11 x 1010 N/m²

To Find: Poisson's Ratio for silver

Solution: Poisson's ratio is the ratio of the transverse strain to that of the axial strain under the influence of the same force. It is a material property and remains constant.

Poisson's ratio is related to Young's modulus and bulk modulus with the given formula:

Y=3K(1−2σ)

putting the value of Y and K

7.25×10^-11 =3×11×10^10 (1−2σ)

σ=0.39

Therefore, Poisson's ratio for silver will be σ=0.39
