Internal Force Diagram, Concept and Example, Normal, Shear and Bending Moment

In this video, the internal force diagram: the normal force, shear force and bending moment diagrams are explained.
The video answers the following questions:
What are internal forces, and why do they exist and what are their types?
What are the internal force diagrams and what do they represent?
and finally how do we draw these diagrams.
A simple beam example is given to show how to simplify the drawing of the diagrams

For a Simple Beam Example with uniform load watch the following lecture:

God willing, more examples will be given in future videos.

To better understand this video, you should have knowledge of internal forces and support reactions.
