## How to Locate Point of Zero Shear

The algebraic sum of all forces either to left or right side of the exact location of the unknown point treating it as ‘x’ and equate it to zero and solve for ‘x’. Ra = wx. The magnitude of Ra …

## How to Find Point of Contraflexure

In an overhanging beam, point of contraflexure is a point where bending moment changes it sign. Example: A point, where bending moment goes from positive to negative or from negative to positive. It can better explained by solving a numerical. …

## Shear Force & Bending Moment Diagram of Simply Supported Beam

Shear force and bending moment diagram of simply supported beam can be drawn by first calculating value of shear force and bending moment. Shear force and bending moment values are calculated at supports and  at points where load varies. Simply …

## Shear Force & Bending Moment of Cantilever With UDL & Point Load

In this example, readers will learn how to draw shear force & bending moment diagram of cantilever beam carrying udl(uniform distributed load) and point loads. Example Draw shear force and bending moment diagram of cantilever beam carrying UDL and point loads. …

## Shear Force & Bending Moment Diagram of Cantilever Beam

Shear force on cantilever beam is the sum of vertical forces acting on a particular section of a beam. While bending moment is the algebraic sum of moments about the centroidal axis of any selected section of all the loads …
