1. The problem statement, all variables and given/known data http://img3.imageshack.us/img3/6618/5n6.jpg [Broken] Image there. 2. Relevant equations Well this is actually where the problem occurs. You make your own equations. 3. The attempt at a solution It's the friction that is really messing me up. I'm just so confused, I'm going to show you my attempt at FBDs for the problem. I think that if I just know how to draw them correctly I'll be able to find my answer, unless there is some other tricky way to get it. Okay so for the 12kg block, we have: m1g going DOWN n1 going UP T to the LEFT fs to the LEFT And for the 7kg bracket, we have: m2g going DOWN n2 going UP n1 going DOWN T to the RIGHT? fs to the RIGHT Apparently I didn't draw them correctly because when I try to solve for something, there are always two variables... other than f = Mu*N which equals 94.08 N.
