Stress & Strain

The constant of proportionality of stress and strain is

Normal Stress

Elasticity: Longitudinal, Shear, Volumetric stress and strain | Elongation of rod under own weight Thermal stress | Elastic energy | Torsion

Elasticity: Longitudinal Stress & strain | Shear stress & shear strain | Volumetric stress and strain

The graph between stress and strain represents the

Consider the given statements to be true and decide which of the given conclusions/assumptions can definitely be drawn from the given statements. Statements : I. Life means stresses and strains. II. Stresses and strains have an adverse effect on life. Conclusions: I. Life is not worth living. II. One should avoid stresses and strains in life.

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.

Assertion: Ratio of stress and strain is always constant for a substance. Reason : This ratio is called modulus of elasticity .
