Question

A material has Poisson?s ratio $0.5$. If a uniform rod made of it suffers a longitudinal strain of $2\times10^{-3}$, then the percentage change in volume is

• A. $0.6$
• B. $0.4$
• C. $0.2$
• D. Zero

Answer 1

Answer: (D)

Zero

Answer 2

As the Poisson?s ratio of a material is $0.5$, so there is no change in volume.
