Answer 1

Answer:

point of contraflexure is a point where the curvature of the beam changes sign. It is sometimes referred to as a point of inflexion and will be shown later to occur at the point, or points, on the beam where the B.M. is zero.

Answer 2

Explanation:

Point of inflection is the point where a curve changes its curvature, that is f''(x) = 0 and f"'(x) not equal to 0. ... That is, the point of contraflexure is for Bending Moment Diagram while Point of inflection is the corresponding point in Elastic curve of the beam and here beam changes curvature
