Hookes law

views updated

Hooke's law The law, named after Robert Hooke, which describes the behaviour of perfectly elastic materials in terms of a straight-line relationship between stress and strain in such materials. Strain is directly proportional to the applied stress provided the medium remains elastic (i.e. the elastic limit is not exceeded); stress is equal to the strain multiplied by a constant of elasticity (Young's modulus). The law also states that stress divided by strain is a constant. See also ELASTIC CONSTANTS.
