Overhanging Beams:

An overhanging beam is a beam that overhangs from the support either one side or both of sides. The overhanging part of the beam shall be treated as cantilever.

Point of Contraflexure

For the reason of shear force and bending moment, the overhanging beam shall be analyzed as a combination of simply supported beam & a cantilever beam. We have explained that the BM is negative for the cantilever & positive for the simply supported beam. This implies that in an overhanging beam, there is a point at which the BM alter from positive to negative and vice-versa. Such as point where the BM changes sign is called as contraflexure. There might be one or more points of contraflexure.
