The shear diagram will also behave as found in the first case of the simple beam. However, now that the ends are fixed, the moment at the supports will reach differently.

This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear ...

Beam diagrams are used as a fundamental way to teach engineers the basic of static loading. Beams are structural elements that are able to withstand load by its resistance to bending.
