Hook’s law: Hook’s law states that stress and strain are proportional to each other under elastic limit. Originally, Hooke’s law specified that stress was proportional to strain but Thomas Young introduced a constant of proportionality which is known as Young’s modulus. Further, this name was superseded by modulus of elasticity. where E is modulus of elasticity, σ is stress, and…
