Point of contra flexure occurs only in overhanging beam.

Answer is B is correct.

Veeresh said:   8 years ago
Point of contraflexure is the point at which shear force changes sign.
OR
BM is zero or max.

In a bending beam, a point is known as a point of contraflexure if it is a location at which no bending occurs. In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero line. In other words where the bending moment changes its sign from negative to positive or vice versa.

Point of inflexion where the shear force changes its sign.

At PCF bending moment will be zero.
