I don't have the solution manual answer for this problem, can anyone help please confirm my answers are correct? 1. The problem statement, all variables and given/known data http://img860.imageshack.us/img860/6118/40893341.jpg [Broken][/QUOTE] On a smooth horizontal weightless surface ABDC acts at the center a vertical force of 600 [N]. The surface is connected to the wall through axes A and B and supported by shaft CE. A) Calculate reaction at CE B) Calculate reactions at axes A and B. Presume the forces at the B axis are at the X and Y direction only. 3. The attempt at a solution This is my solution attempt http://img204.imageshack.us/img204/2712/20112011a.jpg [Broken] http://img834.imageshack.us/img834/6539/20112011b.jpg [Broken]] And here below in the thumbnail I have attached my friend's attempt. He's smart, but new to 3D statics, and I don't understand how what he did makes sense. In fact it contradicts my results and methods.
