1. The problem statement, all variables and given/known data http://img66.imageshack.us/img66/9317/inlinelt8.th.jpg [Broken] 3. The attempt at a solution Sorry, By and B should be in lbs, not lbft http://img141.imageshack.us/img141/9320/pictarsp4.th.jpg [Broken] My work just shows how I attempted to find the force B. According to my book, the force B should be 2140 lb. I'm really not sure if I handled the incline (force B) correctly. I know it's supposed to be perpendicular to the point of contact. Does anyone see where I went wrong? As far as I can tell, the width of the beam (1.2ft) isn't important for finding any of the vector components.
