The following values for a clastic material : Young's `=7xx10^(10) Nm^(-2)` and Bulk modulus `=11xx10^(10) Nm^(-2)` . The poisson's ratio of the material is -

A

0.12

B

0.24

C

0.31

D

0.39

Text Solution

Verified by Experts

The correct Answer is:
D
`K=(Y) /(3(l-2sigma))or 11xx10^(10)=(7xx10^(10))/(3(l-2sigma))`
`or(7)/(33)=1-2 sigma`
`or 2sigma =1-(7)/(33)`
`sigma =(26)/(33)=0.39`
