This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear forces and bending moments are resultants which are used to conveniently ...

In this diagram there are two forces, which, when added together give a resultant force of 30 newtons (N). Resultant force = 20 N + 10 N. Resultant force = 30 N to the right. 2.

There are four forces acting on this block: downward gravitational force, the force from the push, a frictional force, and a normal force from the wall. As a force diagram, it would look like this.

The pure bending shown in the diagram can be produced by applying four forces to the beam, two of opposite direction at each end. This configuration is known as 'four point bending' and produces a ...
