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 te angle between the rods, and the whole hangs in a verticle plane. The contact between the disc and the rods is smooth. The lenght of each rod and of each string is 2a , and 2θ is the angle between the rods. Show that the tension T in each string is given by

2Tcosθ = 2w + W

and that the reaction R between the disc and the rods is (1/2)W cosecθ at each point of contact. Show also that r is related to a by the formula

r = {2a(3w + 2W)/W}sin²θtanθ
