A string is threaded through a smooth ring of weight W and is tied to two points A and B on the same level. The ring is pulled by a horizontal force, P, so that the two parts of the string are inclined at angles of 60 deg and 30 deg respectively to the vertical.
a) draw the two possible configurations which fit the given facts.
This part I understand and the attached graphics are the two configurations.
The next part is bit I am stuck on:
b) Show that in each case the tension in the string is W(root(3) - 1).
