Hook's law :
According to this law , the extension produced in a loaded spring or wire is directly proportional to the load attached to it within elastic limit.
Extension ∝ LoadIn terms of stress and strain, Hook's law can also be stated as,
Stress ∝ Strain
Or Stress = constant × Strain
Or Stress/ Strain = constant = Modulus of elasticity (E)
The ratio of stress and strain for a body is always constant and is called modulus of elasticity or coefficient of elasticity (E). The value of this constant (E) depends upon the nature of the material of the body.
