Attempt any THREE : Derive an expression for strain energy. Hence show that strain energy per unit volume is directly proportional to the square of the stress.

Modulus OF Rigidity|| Bulk Modulus|| Stress-Strain curve

Define the terms stress and strain and also state their SI units. Draw the stress versus strain graph for a metallic wire, when stretched upto the breaking point.

Statement-1 : The value of moduli of elasticity is directly proportional to stress. Statement-2 : The value of moduli of elasticity is inversely proportional to strain. Statement-3 : The value of moduli of elasticiy is independent of magnitude of stress and strain.
