Shear & Moment Equations | Triangular Load on Simply Supported Beam (Method of Sections)

Shear Force and Bending Moment (Example 7)

In this series of videos, I'll explain how you can write expressions for the shear force and bending moment of different types of beams as functions of x, and using those functions, you will be able to draw accurate shear force and bending moment diagrams for the beams.

In the seventh example, I'll utilize the same concept used in the previous videos to write expressions for the shear force and bending moment as functions of x and draw their diagrams for a simply supported beam with a triangular load applied over the length of the beam.
