1. The problem statement, all variables and given/known data http://img151.imageshack.us/img151/6641/torquebk4.jpg [Broken] 2. Relevant equations T=F*r F*X=Ia I=ML2/3 3. The attempt at a solution I was able to do part A easily enough, but I'm not quite sure where to even start with part B. I know that the force on the pivot point would be F0 if X was .5L, ie the center of mass. However, I am unable to come up with the equation asked for. Thanks for any help!
