1. The problem statement, all variables and given/known data A 12.0kg box resting on a horizontal, frictionless surface is attached to a 5.00 kg weight by a thin, light wire that passes over a frictionless pulley. The pulley has the shape of a uniform solid disk of mass 2.00 kg and diameter 0.500 m. After the system is released, find the horizontal and vertical components of the force that the axle exerts on the pulley. 2. Relevant equations F=ma (?) 3. The attempt at a solution I have already calculated the tension in the wire on both sides of the pulley (x =32.6N and y=35.4 N) and the linear acceleration which equals 2.72 m/s2. I know that this question has been asked previously, but I still don't understand what teh force exerted on the pulley by the axle is. Am I just trying to find Fx=m (alphax) and Fy=m(alpha y)?
