A 3m long steel wire is stretched to increase its length by 0.3cm. Poisson's ratio for steel is 0.25. What is the lateral strain produced in the wire?

A

`2.5xx10^(-4)`

B

`1.25xx10^(-4)`

C

`5xx10^(-4)`

D

`7.5xx10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Lateral strain `= sigma(delta L)/(L)`
`= (0.25 xx 0.3 xx 10^(-2))/(3) = 2.5 xx 10^(-4)`
