1. The problem statement, all variables and given/known data
Using a uniform strut, a rigid brace hinged at the floor, a person holds a 30kg engine in equilibrium while it is being repaired. The strut has a mass of 12.5 kg. A smooth rope passes over a pulley at the end of the strut. (a) What is the force exerted on the rope by the person? (Specify the direction of this force by calculating the angle theta that the rope makes with the horizontal.) (b)What forces are exerted by the strut? 2. Relevant equations Fx=0 Fy=0 T=rF=0 3. The attempt at a solution Looking at the engine, Fy=0 so Tension=mg. I don't know where to go from here.
