Two equal rods of weight w are freely jointed and their free ends are attached by strings to a fixed point.
A circular disc of weight W and radius r rests in the angle between the rods and the whole hangs in a vertical plane. If 2a is the length of each rod and each string and 2θ the angle between the rods, prove that
r = [2asin^2θtanθ(3w+3W)]/W
