If the values of Y and eta for a materi...

If the values of Y and `eta` for a material are `2xx10^(11)` pascal and `8xx10^(10)` pascal respectively, then the value of Poisson's ratio `sigma` will be

A

0.52

B

0.25

C

1.25

D

-0.25

Text Solution

Verified by Experts

The correct Answer is:
B
`y=2 eta (1+sigma)`
`1+sigma =(y)/(2 eta)=(2xx10^(11))/(2xx8xx10^(10))`
`1+sigma=1.25`
`sigma =1.25-1`
`=0.25`.
