The question is:

On a model ship, the mast OC has length 50cm and weight 20 newtons. The mast is hinged to the deck at O, so that it can rotate in the vertical fore-and-aft-plane of the ship. Small smooth rings are fixed at the points A and B on a deck in this plane such that AO = OB = 50cm. Threads from C are passed through these rings, and held at their ends by two children who exert forces of P newtons and Q newtons respectively. If Q = 10, calculate the value of P needed to hold the mast in equilibrium at 40 degrees to the horizontal deck.

The diagram is:


Any help is appreciated!
