A beam is supported by a pin connection at D and a roller support at B. An leftwards force Fi = 44 lb acts at the left end of the beam (point A). A uniformly distributed load 12.0 lb/ft pushes down on the beam between points A and C. The distributed load increases linearly from point to a value of w1 = 17.2 lb/ft at the right end of the beam (point D). The separation between A and B is L1 = 1.6 ft, and the separation between C and D is L2 = 4.9 ft. Determine the vertical component of the reaction force at point B. Assume upwards forces are positive. W1 12.0 lb/ft F1 А B с D L 3.0 ft L2
