Practice problem-7-32, from Prof. Timothy Philpot's book, An Integrated Learning System, Mechanics of Materials. Use the discontinuity function for load, shear, and moment functions.
A step-by-step guide to driving the expressions for W(x), V(x), and M(x) for a given beam acted upon by two concentrated loads, using the discontinuity function.
Use the information from V(x) and M(x) to draw the shear and moment diagrams.
An Excel sheet is used to derive the same values using if, then, and command.
The video has a closed caption in English.
