The term CAPSTAN is a mechanical device used to apply force to a rope or cable. It consists of three parts: a RUNDLE, which is a cylindrical shaft with a handle on one end; a WINDLASS, which is a wheel-like device that is turned to wind the rope or cable around the capstan; and a PAWL, which is a lever that locks the WINDLASS in place. Together, these three components work together to provide the necessary force to move the rope or cable.
