1. The problem statement, all variables and given/known data Determine the magnitude of F if the resultant of the three forces passes through point O. 2. Relevant equations ƩFx = 0 ƩFy = 0 ƩM = 0 3. The attempt at a solution The most I can come up with is that the two forces on the left would equal F on the right, and trying to ratio the force and distance it still does not work. Any hints would be greatly appreciated.
