Hookes Law

Hooke's Law Stated That Within Elastic Limit, The Linear Relationship between simple stress and strain for a bar is expressed by equation

                                    Stress ∝ Strain

                                          σ = E ε
                                    
                     Where,
                                  σ = is the axial normal stress
                                  ε = is the axial normal strain
                                  E = is the modulus of elasticity or Young's Modulus

 Hooke's law for shear

                                ፒ = G Ø

                   Where,
                               ፒ = is the shear stress
                               Ø = is the shear strain
                               G = is the modulus of rigidity or (shear modulus)
