I hope it is helpful for you..

Answer 2

Answer:

The point of contra flexure(POC) is a center point of the beam where it bends at zero. it is due to compression or tension the change happens from positive to negative or vice versa.

Explanation:

When a load is applied to a beam it bends and the bending moment changes from positive value to a negative value or vice versa.

The point of contraflexure is determined as the point in where the bending moment is zero.

To know the exact point of contraflexure, the bending moment diagram should be drawn. The point of contraflexure is maximum when the shear force is zero.
