The Poisson's ratio of the material of a...

The Poisson's ratio of the material of a wire is 0.25. If it is stretched by a force F, the longitudinal strain produced in the wire is `5xx10^(-4)`. What is the percentage increase in its volume?

A

0.2

B

`2.5xx10^(-2)`

C

Zero

D

`1.25xx10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
C
When a wire is stretched, there is a slight increase in its length and a slight decreases in its diameter. But its mass, density and volume remain constant.
`:.` Pressure increases in volume = 0
