1. The problem statement, all variables and given/known data http://img713.imageshack.us/img713/5719/59623631.png [Broken] 3. The attempt at a solution http://img441.imageshack.us/img441/6480/74300117.png [Broken] I would just like to know whether I am starting the question correctly. I'm not exactly sure whether my loop equation is right since I don't have the third link involved. But, I don't know how else to write the loop equation. I would appreciate it if someone could check my diagram and loop equation and tell me if I'm going the right direction.
