Pulleys


Pulleys are simple machines that consist of a grooved wheel and a rope or cable that runs along the groove. They are used to transmit power and motion between rotating shafts and can be found in various maritime applications such as cranes, winches, and hoists. Pulleys can be fixed or movable and can change the direction of force applied to the rope or cable. They are often used in combination with other simple machines such as gears and levers to increase mechanical advantage and make tasks easier to perform.
