Give the relation between shear modulus $(G)$ and Young's modulus $(Y)$ for an isotropic material.

Which of the following is the correct relation between Young's modulus $(Y)$ and Poisson's ratio $(\sigma)$?

$A$ 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

If there is no change in the volume of a wire upon stretching,then the Poisson's ratio for the material of the wire is:

For silver,Young's modulus is $7.25 \times 10^{10} \ N/m^2$ and Bulk modulus is $11 \times 10^{10} \ N/m^2$. Its Poisson's ratio will be

A compressive force is applied to a uniform rod of rectangular cross-section so that its length decreases by $1 \%$. If the Poisson's ratio for the material of the rod is $0.2,$ which of the following statements is correct? "The volume approximately ..........."
