1. The problem statement, all variables and given/known data 2. Relevant equations T=Fl 3. The attempt at a solution I'm not sure what the moment arm of this problem is. I think it is suppose to be a line connecting 0 to F1 at a right angle. To draw this moment arm one would have to extend F1 past where it meets A. However I am not sure is that is the right moment arm, how to find that distance, or how the other forces come into play for this problem.
