Point of contra flexure occurs only in overhanging beam.

Answer is B is correct.

Ashish said:   8 years ago
As per point of contra flexure definition. It is the point where the B.M is Zero after changing its sign from +ve to -ve value or vice versa.

So, answer B is correct (Bending moment diagram).

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.

The Poc is the point at which bending moment changes its sign.

Point of contraflexure is point where Shear force changes its sign and at that point BM is max.

Vinod said:   10 years ago
The point of contra flexure is a point where BM is zero.

i.e bending moment changes sign.

Answer is wrong and right answer is sf is change its sign.

Saurabh said:   10 years ago
Point of contra flexure, where BM changes its sign on BM graph. At this point the SF will be Max.
