okay here is the problem.. A 60kg mass is suspended from a rope which is threaded over a mass less pulley and then attached to a hook on a vertical wall. Describe a free body diagram for the mass and another for the hook and show how each is in equilibrium. Okay..so there is a force between the hook and the pulley, but what about the hook and the wall? HELP!!

Of course. Otherwise the hook would not be needed to resist the force from the pulley. The pulley could just float in the air and you know they don't do that.

Firstly anything "frictionless" or "massless" does not exist. The force on the wall hook is equal to the load, i.e. 60kg
