    - 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.

    - Actual breaking stress: It is defined as the stress which is calculated by dividing respective loads with reduced cross-sectional area.

    - Actual breaking stress is higher than ultimate stress, in a stress-strain curve.
