Hooke’s law

Mechanical Engineering

Hooke’s law:

It states that when the material is loaded within the elastic limit the stress is directly proportional to strain.

i.e. Stress α strain

or Stress = Constant x Strain

or Stress = Modulus of elasticity x Strain

or Stress/Strain = Modulus of elasticity

In the figure the material obeys the hooke’s law up to point A.
