The bending moment diagram for an ‹overhanging beam is shown in the figure.  The  points of contra flexure would include Correct Answer C and D

Concept:

The point of contra flexure would include both C and D.

  • In a bending beam, a point of contra flexure is a location where the bending moment changes its sign.
  • In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero line. 
  • At the point of contra flexure, the bending moment is zero.
