For a given material, the rigidity modulus is `((1)/(3))^(rd)` of Young's modulus. Its Poisson's ratio is

A

0

B

0.25

C

0.3

D

0.5

Text Solution

Verified by Experts

The correct Answer is:
D
The relationship of Poission.s ratio, rigidity and Young.s modulus is
`eta = Y/(2(1 - sigma)) sigma` - Poisson.s ratio
Here, `" " eta 1/3 y implies 3 eta = y`
Substituting the value, we get `sigma = 0.5`
