Homework Statement
Find the potential energy function for the three mass, earth, and pulley system as shown. The potential energy will be as a function of the vertical position downward as shown in the diagram. Also, find the equilibrium position of this system. The two outside masses are equal.

The Attempt at a Solution
Actually I do not conceptually understand this question. Why would the gravitational potential energy ΔGPE change based on what y is?
I guess we could do ΔWnet=ΔKE+ΔGPE and we could make the system everything so that it is equal to 0 so 0=ΔKE+ΔGPE, but I don't see what is CHANGING in the problem. Everything looks static to me
