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 point of contra flexure means bending moment change in sign from +ve to -ve or -ve to +ve at that time bending moment is zero and shear force is maximum and point of contra shear mean shear force change in sign and that time shear force is zero and bending moment is maximum.

The bending moment is maximum at a point where shear force changes sign. This means that the point where shear force becomes zero from +ve to -ve value or vice versa, the B. M. At that point is maximum.
So, answers A & D are the correct answers.
So, answers A & D are the correct answers.

A point is known as a point of contraflexure if it is a location where bending moment is zero (changes its sign). In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero line.

POC is a point in the bending moment diagram where bending moment change its sign i.e. from +ve to -ve or vice versa. By this we can come to a conclusion that poc is a point where bending moment is zero.

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

Point of contract flexure isn't an point where bending momentum changes its sign i.e BM=0 and maximum BM occurs at shear force zero i.e shear force changes it's sign.

Point of contracture is the point at which BM changes its sign.
Point of inflexion where the shear force changes its sign.
Point of inflexion where the shear force changes its sign.
