Usually I'm pretty good with torque and such but this one had me. A box of mass 75 kg is put on a 10-m long steel beam of mass 150 kg and is connected to the wall and supported by a steel cable. The box is located 2.5 m from the wall and the cable makes 60o angle with the beam. What are the magnitude and the direction of the force exerted by the wall on the beam? 2. Relevant equations Torque=Radius x Force, upwards/clockwise torque=downwards/counterclockwise torque, weight=mass x gravity 3. The attempt at a solution I was able to find the tension in the cable, if that helps (14321.475N), but otherwise I'm clueless.
