If longitudinal strain for a wire is 0.03 and its Poisson's ratio is 0.5, then its lateral strain is

A

0.003

B

0.0075

C

0.015

D

0.4

Text Solution

Verified by Experts

The correct Answer is:
C
Poisson.s ratio, `sigma = ("Lateral strain")/("Longitudinal strain")`
`:.` Lateral strain = Longitudinal strain `xx sigma`
`= 0.03 xx 0.5 = 0.015`
