The strain energy per unit volume of a stretched wire is

Give the expression for Young's modulus of elasticity pretaining to a stretched wire.

If x longitudinal strain is produced in a wire of Young's modulus y, then energy stored in the material of the wire per unit volume is

A wire of initial length L and area of cross section A has Young's modulus Y of its material. The wire is stretched by a stress 5 within its elastic limit. The stored energy density in the wire will be

The ratio of the lengths of the two wires of same Young's modulus and same diameter is 5:3 . They are stretched by the same force. Then the ratio of the work done on the two wires to stretch is

A wire of length L and cross-sectional area A is made of material of Young's modulus Y. The work done in stretching the wire by an amount x is

If x longitudinal strain is produced in a wire of Young's modulus Y, then potential energy stored in a material of the wire per unit volume is ..........

If x is the strain produced in a wire having the Young's modulus Y, then the strain energy per unit volume is
