1. The problem statement, all variables and given/known data Determine the magnitude and direction (theta) of F in the diagram of 2. Relevant equations ΣFx = 0 ΣFy = 0 F = ma 3. The attempt at a solution I tried using the sum of components but I end up with three variables and two equations. I've always had issues with figuring out tension through a pulley system. I'm hoping for some insight as to what parts of the diagram are relevant to finding F. So far I've figured F(ab) = cos45(98N) = 138.6N but I can't figure out how to relate that to F and Fac and Fcd. is Fcd equal to ΣFy? This is from my statics book and my physics text isn't helping either. Any clues are appreciated, thanks.
