1. See figure below. A beam AB is simply supported and subjected to a concentrated force P at the mid-span and a distributed load of intensity q over one-half of the span. Neglect the weight of the beam. (a) Find the reactions at A and B. (10) (b) Find the internal shear force and bending moment at a section of distance 20 inch away from B. (10) (c) Draw the shear force and bending moment diagrams for the entire beam AB. Mark the maximum bending moment and its location. (10) Answers: (a) A y = 70 lb and B y = 170 lb; (b) V = - 70 lb and M = 2400 lb-in; (c) see next page.
