Extract

If we suspend a weight by two wires, and turn the weight suspended from its position of repose through an angle υ by means of any force, the wires will no longer be vertical, and the weight will be lifted from its lowest position by a gravity equal to l sin i tan i where l is the length of a wire and i is the small angle which it makes with the vertical.
