When the heavy weight suspended and removed from the metal wire, it cannot get original length. Why?

Text Solution

Verified by Experts

When metal wire is subjected to a deforming force and removed it in elastic limit, the wire regains its original dimension but wire loses the elastic properties beyond the elastic limit if more deformation occur from it.
