To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).

Stays, lines, ropes and halyards.

Split the system first. Divide the weight based on the distance from the center of mass for a uniform solid. For each part of the system the force downward will be the the partial weight.Next, (this is easy if the ropes are vertical) you find the force on each rope by using trigonometry. The force on the ropes will be the hypotenuses of the triangle formed by the downward force and its angle.Notice that, as the angles (θ and θ') of the ropes approach 0° (horizontal), the force on the rope approaches infinity.
"On the ropes" is a colloquial term passed from boxing competitions, where a contestant was groggy, and holding onto the ropes round the ring for support. The implication is of being overcome, of weakness and distress.
