Strain energy per unit volume of a stretched wire is ` 5 xx 10^(-3) J/m^3` . If Y = `9 xx 10^10 N/m^2` for the material of the wire , find the tensile stress and strain in the wire .

A 5 kg wt is suspended from the end of a wire 2.5 m long fixed to a rigid support. The diameter of the wire is 2 mm. If Y = 20 x 10^10 N/m^2 for the material of the wire, find the increase in its length.g = 9.8 m/s^2 .

The diameter of a wire decreases by 5% when the wire is subjected to a stress of 8 xx 10^10 N/m^2 . If sigma = 0.5 for the material of the wire, find Y .

Young's modulus of the material of a wire is 9.8 x 10^10 N/m^2 and the area of cross-section of the wire is 0.012 cm^2 . Elastic limit of the material of the wire is exceeded when the strain exceeds 1/2400 . Find the maximum load that can be used to stretch the wire without causing a permanent set.

For silver, young's modulus is 7.25 xx 10^10 N/m^2 and bulk modulus is 11 xx 10^10 n/m^2 . What is the poisson's ratio ?
