Question

Explain the concept of elastic potential energy in a streched wire and hence obtain the expression for it

Answer 1

Answer:

The work done by external applied force during stretching is stored aspotential energy (U) in the wire and is called as strain energy in the wire. This is an expression for strain energy orpotential energy per unit volume ofstretched wire. This is also called as the energy density of the strained wire.
