Video for practice problem P7-38-Use discontinuity Function.
Write the expressions for W(x),v(x), and M(x) for the given beam. Use these data to plot shear and moment diagrams. The beam is acted upon by a point load, point moment, and a uniform load with limited width. The beam is simply supported and has a concentrated load, a concentrated moment, and a partial uniform load.
