Elastic Potential Energy Stored In A Stretched Wire

A block of mass M is suspended from a wire of length L, area of cross-section A and Young's modulus Y. The elastic potential energy stored in the wire is

When a block of mass M is suspended by a long wire of length L, the elastic potential energy stored in the wire is 1/2xxstressxxstrainxxvolume. Show that it is equal to 1/2Mgl where 1 is the extension. The loss in gravitational potential energy of the mass earth system is Mgl. Where does the remaining 1/2Mgl energy go ?

A weight Mg is attached to the free end of a wire suspended from a rigid support. The wire is extended by l. The ratio of the elastic potential energy stored in the stretched wire to the work done by the weight Mg is

A wire 2 m in length suspended vertically stretches by. 10 mm when mass of 10 kg is attached to the lower end. The elastic potential energy gain by the wire is (take g = 10 m//s^(2) )

A mass m is suspended from a wire . Change in length of the wire is Deltal . Now the same wire is stretched to double its length and the same mass is suspended from the wire. The change in length in this case will become (it is suspended that elongation in the wire is within the proportional limit)
