| A: If the volume of a body remains unchanged, when subjected to tensile strain, the value of Poissons ratio is \[\frac{1}{2}\] |
| B: Phosphor bronze has low Youngs modulus and high rigidity modulus. |
A) A and B are correct
B) A and B are wrong
C) A is correct and B is wrong
D) A is wrong and B is correct
Correct Answer: C
Solution :
We know that value of Poissons ratio is 0.5, when the change in volume is zero or volume remains constant, therefore, statement is correct. Phosphor bronze is a alloy and it has a high Youngs modulus and has low modulus of rigidity. Hence, statement B is wrong.
