1. The problem statement, all variables and given/known data http://img835.imageshack.us/img835/7509/appearsimple.jpg [Broken] Long story short: A is fixed to the ground. Point C is a pin joint. W = 200 [N] The rest is what you see is what you get. 3. The attempt at a solution I get too many unknowns no matter what I do. If I look at only external forces (Which is what we were told to do with every "frame" problem such as this, this is what happens: Sigma Ma = 1.5W - 1.5By +Ma = 0 (2 unknowns!) If I do sigma Mb, I get 3 unknowns! I can't build enough equations with similar unknowns to solve systems of equations. Even when I look at each member individually I don't have enough to solve for anything.
