Three masses are constrained to lie on the edges of a triangle. Equal constant force actuators (with force F) are attached to each pair of masses. When this system finds equilibrium, the potential energy will be at a minimum. However, the PE in each actuator is simply F times L, where L is the length of the actuator.
Hence minimum PE is achieved when the masses sit at the vertices of the mi…
