Homework Statement
Consider the situation of the figure, where a string of negligible mass and length L is fixed at two points A and B, with B dislocated of A by a distance w(<L) and vertically dislocated by a distance h < sqrt(L^2-w^2) A mass is hung on the rope using a moving pulley of negligible mass. The pulley has no friction and can move freely along the rope until it "finds" the position of equilibrium in which the pulley is at a horizontal distance x of point A, and a vertical distance y of that point.
What are the equilibrium angles Theta(1) and Theta(2)?
What are the values of x, y , L1 and L2 at equilibrium?
Homework Equations
There aren't any besides the fact that the potential energy must be a minimum
