1. The problem statement, all variables and given/known data 8. A 20 kg uniform beam 10m long is attached to a wall with a cable. The cable is attached to the middle of the beam at a 90 degree angle to the beam. A box of mass 5 kg is also suspended from the beam. In addition to this, the beam is attached to the hinge at the bottom. Solve for: Tension in cable and total force acting on the hinge. 2. Relevant equations Torque = Force * Distance 3. The attempt at a solution So, I was able to determine the tension in the cable by finding the magnitude of all the forces in a perpendicular direction to the beam, then used those perpendicular forces multiplied by their distance to the hinge in a torque equation to determine the tension in the cable. However, I am completely stumped as to how I would determine the force acting upon the hinge. I would imagine that the whole system is in equilibrium and is unmoving (as this in on a section related to torque and rotational equilibrium), so I think the trouble that I'm having here is figuring out exactly what forces are acting on the hinge, and why they are doing so.
