im not too sure what the bead is for ....  but as i see it, there are 2 equal forces in the downward direction that are each, half the weight of the ring (F = mg/2)

knowing the Force down is proportional to the lengths of the corresponding triangles:

30*n = Force down

50*n = Force in string (tension)
