Shear force and bending moment diagram example #5: mixed distributed and point loads

This engineering statics tutorial goes over an example of a simply supported beam with a mixture of point loads and distributed loads. In order to draw the shear force diagram (SFD) and bending moment diagram (BMD), we first need to draw a free body diagram (FBD) of the whole structure to solve for the reactions. Then we take a few virtual cuts on each side of major changes along the beam, which are before and after any point loads, and any start or stop of a distributed load. With a few steps, we’re able to draw the SFD and BMD for the whole beam.
