Question

The strain energy stored in a hollow shaft of outer and inner diameters

Answer 1

When a body will be loaded then there will be deformation in the body and due to this deformation, energy will be stored in the body and that energy will be termed as strain energy.

Let us see the basic definition of the strain energy

Strain energy is basically defined as the internal energy stored in the body when body will be subjected with a load within its elastic limit.

We must have to be ensuring that load applied over the body must be within its elastic limit i.e. after removal of load; body must secure its original dimensions.
