Point of contraflexure where the bending moment changes its sign from negative to positive or vice versa.

Point of contra flexure, where BM changes its sign on BM graph. At this point the SF will be Max.

Prasad said:   1 decade ago
Point of contraflexure is point where Shear force changes its sign and at that point BM is max.

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

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

i.e bending moment changes sign.

POI is the point at which BM is zero. POC is the point at which BM changes its sign. :).

I agree to @Naresh. Point of contraflexure is that point where BM changes it's sign.

Point of contra flexure occurs only in overhanging beam.

Answer is B is correct.
