A material has Poisson's ratio 0.50. If a uniform rod of it suffers a longitudinal strain of \(2 \times 10^{-3}\), then the percentage change in volume is
- A 0.6
- B 0.4
- C 0.2
- D zero
Answer & Solution
Correct Answer
(D) zero
Step-by-step Solution
Detailed explanation
Hints : Poisson's ratio is 0.5 so there is no change in volume
