The longitudinal stain in a metal bar is 0.05. If the Poison's ratio for this metal is 0.25, then the lateral strain will be

A

0.25

B

0.75

C

0.05

D

0.0125

Text Solution

Verified by Experts

The correct Answer is:
D
`sigma=("Lateral cont strain")/("Long ele strain")`
`therefore " Lateral cont strain"=sigma xx "Long ele strain" `
`=0.25 xx 0.05`
`=0.0125`.
