a beam is supported by a pin support at A and a roller support at B. For this question, leave your answer in terms of the variables w and L. (a) (b) First section: Make an arbitrary cut between points A and B. Take the distance of the cut to be x along the beam from point A. Draw the free-body diagram for the left section and find functions for the internal shear force, V(x), and bending moment, M(x), in the section of the beam between A and B. (c) Second section: Repeat part (b) for the section of the beam between B and C. Take x to still be the distance from point A. (d) Using equilibrium of the full beam, find the support forces at A and B. O (f) Find the value of x at which V(x) = 0. The internal bending moment reaches a maximum at the same point as V(x) = 0. Find the maximum bending mo- ment. A pin Sketch the shear and bending moment diagrams. B L W roller
