1. If cylinder E weighs 30lb and theta = 15 degrees, determine the weight of cylinder F 2. Sigma F = 0 (Statics question) 3. I have gotten my separate components but I don't know how to solve the equations this sounds really stupid since I'm in calc III and physics II but my brain is just crapping out on me. I have attached a sketch of the problem The only thing(s) that are given are the three angles, and one weight. I am having a hard time figuring out how to solve these equations. So far I have Sum(x) = 0 = -Fab cos30 + Fbc cos15 Sum(y) = 0 = Fbc sin30 - 30 - Fab sin15 I even have the solutions on hibbeler however I want to learn how to solve these equations, its definitely a basic concept that I should know how to do, that is solving trig problems.
