How is elastic potential energy stored and released?

The elastic potential energy of a spring

Derive an expression for the elastic potential energy stored in a stretched wire under stress.

A uniform wire of length L and radius r is twiste by an angle aplha . If modulus of rigidity of the wire is, then the elastic potential energy stored in wire

When a block of mass M is suspended by a long wire of length L, the length of the wire becomes (L+l). The elastic potential energy stored in the extended wire is

Elastic Potential Energy Stored In A Rod

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 system comprises of two small spheres with the same masses m . initially, the spring is non deformed. the spheres set in motion in a gravity space at the velocities as shown in the diagram. The maximum elastic potential energy stored in the system is

A uniform rod of mass M and length L, area of cross section A is placed on a smooth horizontal surface. Forces acting on the rod are shown in the digram Ratio of elastic potential energy stored in section PQ and section QR of the rod is

A wire suspended vertically from one of its ends is stretched by attaching a weight of 100 N to its lower end. What is the elastic potential energy stored in the wire, if the weight stretches the wire by 1.5 mm ?
