STRESS IN MATERIAL
Stress ⇒ Stress is internal resistance offered by material against the deformation.
→ We applied load P on bar than there will be some deformation in material, material resist this deformation.
Now. Cut, a section for internal forces.
Stress (σ) =Pinternal/(Cross sectional area)
(σ=Pint/Ac )
Classification of Stress –
