1. The problem statement, all variables and given/known data 2. Relevant equations The book says that Torque = the length of the moment arm X the magnitude of the vertical component of F = r X F 3. The attempt at a solution My problem is that I don't have any vectors to do a cross product. Instead I tried to just multiply what I know: 50lbs x 9in x sin60° ≈ 389.71ft-lb which is far from the correct answer, 32.5ft-lb. The problem seemed simple enough so am I making some small mistake or going about this completely wrong?
