ELASTIC POTENTIAL ENERGY STORED IN A STRETCHED WIRE

Elastic Potential Energy Stored In A Rod

Hooke's Law | Modulus of Elasticity and Potential Energy Stored

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 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 ?

Assertion: Work is required to be doen to stretch a wire. This work is stored in the wire in the form of elastic potential energy. Reason: Work is required to be done against the intermolecular forces of attraction.

A wire suspended vertically from one of its ends is stretched by attaching a weight of 200 N to the lower end. The weight stretches the wire by 2mm. The elastic energy stored in the wire is
