Question

The Poisson's ratio $\sigma$ should satisfy the relation :

• A. -1< $\sigma$ < 0.5
• B. -0.5 < $\sigma$ < 1.0
• C. 0.5 < $\sigma$ < 1.0
• D. -1.0 < $\sigma$ < -0.5

Answer 1

The correct option is A -1< $\sigma$ < 0.5

Poisson's ratio is the ratio of transverse contradiction strain to longitudinal extension strain in the direction of stretching force.

The Poisson's ratio $\sigma$ should satisfy the relation,

$-1<\sigma <0.5$
