Can materials be exempt from hooke's law
WebJul 1, 2024 · According to Hooke’s law, elastic behaviour of a material is partly due to small displacements of its constituent molecules. These displacements are also proportional to the force caused by displacements themselves. The skin is defined as perfectly elastic as it returns to its initial shape after applied forces. WebHooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an …

The disadvantages of Hooke’s Law is as follows: 1. Hooke’s Law is applied only in the elastic region. 2. Hooke’s Law gives accurate results only for solid bodies if the forces and … See more When a material behaves elastically and exhibits a linear relationship between stress and strain, it is called linearly elastic material. In this case, stress is directly proportional to strain. … See more The applications of Hooke’s Law is as given below: 1. Most commonly, in everyday life, Hooke’s Law is applied in springs because of their elasticity. 2. They are used not only in the engineering field but also used in the … See more Hooke’s equation holds in many situations where an elastic body is deformed.
