If for a material
Young's modulus = `6.6 xx 10^10 N m^-2` and Bulk modulus =`1 1 xx 10^10 N m^-2`, its Poisson's ratio is

A

0.1

B

0.2

C

0.3

D

0.4

Text Solution

Verified by Experts

The correct Answer is:
D
Poisson's ratio, `sigma= 1/2(1- E/(3K))`
`=1/2 (1-(6.6xx10^(10))/(3xx11xx10^(10)))`
`=1/2 xx 0.8 = 0.4`
