MediumWrite the limitation of Hooke's law.
(N/A) Hooke's law states that stress is directly proportional to strain within the elastic limit. The limitation of this law is that it is only valid for small deformations where the material remains within its elastic limit. If the stress exceeds the elastic limit,the material undergoes permanent deformation (plastic deformation) and the linear relationship between stress and strain no longer holds.
