Point of inflection is that point where any curve changes it's sign. But point of contraflexure is that point where bending moment changes it's sign.

Inflection is a point where the curvature of the bending moment changes the sign not S.F its wrong.

Contaflexure is pt where B.M changes sign.

Meaning of contraflexure is contra opposite and flexure means bending totally it means zero bending moment or change in sign of bending moment.

Inflection : If we extent the line from the point of cotrflexure to the load beam, then that point on loaded beam is point of Inflection.

#POC is that where the shear force change its sign not bending moment and in this case bending moment is usually the maximum.

Point of inflection is where shear force changes sign.

Point of contraflexure is where bending moment changes sign.

@siddhardth sigh lamba.

It completely depends on where the external moment occurs and what is its direction.

In BM diagram sign changes from +ve to -ve & becomes zero is called point of contraflexure.

Rahul Kumar singh said:   7 years ago
Point of inflection is for elastic curve whereas point of contraflexure is for Bending moment.

Contraflexure is the point where bending moment changes its sign, and the value of it is zero.
