In this formidable weapon, the long end of an arm on a pivot was hauled or winched down and then released, allowing a heavy counterweight at the short opposite end of the arm to drop and swing the long end upward through a vertical arc. An exception was the medieval trebuchet, powered by gravity. Nearly all catapults employed in ancient and medieval artillery operated by a sudden release of tension on bent wooden beams or of torsion in twisted cords of horsehair, gut, sinew, or other fibres. The term catapult too can refer to these weapons, but more often it designates a larger engine that is used to hurl stones from a single long arm swinging through the vertical plane.
