Statement-I: If the volume of a body remains unchanged, When subjected to tensile strain, the value of Poisson's ratio is

1 / 2

Statement-II: Phosphor bronze has low Young's modulus and high rigidity modulus

View answer and explanation

Correct option: B

Statement I is true and statement II is false

Statement I is true because when volume is unchanged under tensile strain, Poisson's ratio is 0.5. Statement II is false because phosphor bronze has high Young's modulus and low rigidity modulus.
