Aforce of 40n is applied at the end of a wire 4m long and produce an extension of 0.24mm if the diameter of the wire is 2mm. calculate the stress and strain of the wire

If a force of 40newton is applied to the end of a wire 4m long and produces an extension of 0.24mm. If the diameter of the wire is 2mm, calculate the strain energy

Explanation:

stress=force/area (n/m^2)

strain=deformation/length (m/m)
