In some cases the mechanical work done by a force is converted to elastic
potential energy in a spring. Potential energy (in a spring or in a
gravitational field) can later be recovered:
Consider a body subject to a simple axial load:
The above is correct for situations where axial stresses dominate, as in
column compression or simple beam bending. This does not take shear strain
energy into account.
