WebbAt the point of contraflexure, the bending moment is zero. For example: A propped cantilever beam with uniformly distributed load over the entire span. The corresponding BMD is. At distance L/4 from the left support, we get point of contraflexure, as there is the change in sign. At that point, the Bending moment is zero.
