Vedclass · Answer

(D) Poisson's ratio $(
u)$ is defined as the ratio of lateral strain to longitudinal strain.For most metals,when a force is applied in the longitudinal direction,the lateral dimension decreases,resulting in a positive value for Poisson's ratio.The theoretical limits for Poisson's ratio for stable,isotropic materials are between $-1.0$ and $0.5$.However,for most practical metals,the value is positive and typically ranges from $0$ to $0.5$.Therefore,the correct range for metals is $0$ to $0.5$.

The minimum and maximum values of Poisson's ratio for a metal lie between
