| The restoring force per unit area set up inside the body is called stress and is measured by the magnitude of the deforming force acting on unit area of the body when the equilibrium is established. | ||||

Stress : It is the force of internal resistance offered by a body
against the deformation due to external loads.
1. Normal stress or direct stress (s) : Stress acting normal to a section due to axial forces. (tensile or compressive forces) σ = P/A 2. Shear Stress (t) : Stress due to tangential forces. τ = F/A 3. Bending Stress (fb) : Stress due to bending. fb = M/Z Z = sectional modulus = I/Y 4. Torsional Stress : Stress due to torsion.
