    - Stress: It is defined as the internal resistance set up per unit cross-sectional area.

    - Strain: The ratio of change in dimension to original dimension of the member is called as strain.

    - Modulus of elasticity is also known as Young's modulus (E). It is defined as the ratio of stress to corresponding strain. Strain is a dimensionless quantity.

    - S.I. unit of Young's modulus is N / mm2.

    - Young's modulus (E) = stress / strain

    - A material having high modulus of elasticity is considered as rigid.
