Some examples of pulleys are cranes and flagpoles. Both cranes and flagpoles have a pulley at the top of their poles.Know More
A pulley, which is a basic machine, usually has a rope and a wheel. One end of the rope is tied to the load, while the other end is fitted into the wheel. When the pulley is pulled on one side, the wheel turns, which will move the load. A pulley makes it easy for moving loads sideways, up or down.
A pulley is considered a type of lever, and the pulley's center acts as the fulcrum. The load is at one end, and the effort is at the other end. A block and tackle is a system that has more than one pulley.Learn more about Motion & Mechanics
A pulley works by changing the direction that force must be applied to lift an object against gravity. Other, more complex, systems use multiple pulleys to reduce the amount of force that must be applied.Full Answer >
Pulleys are used in a variety of ways to afford mechanical advantages in lifting heavy loads, applying forces, and to transmit power. In the real world, the usages of pulleys are seen in different load carrying activities. Simple pulleys are used in lifting building materials at construction sites, hoisting a flag, elevators and other simple load-carrying tasks. Compound pulleys are used in cranes, industrial material handling systems and lawn mowers.Full Answer >
Elevators use pulleys as they move the passenger compartments up and down from one floor to the next. Drapery and window blinds also use pulleys -- much smaller than the ones for elevators -- to move the blinds or drapes around.Full Answer >
A pulley is a simple tool that can be used for many things, such as lifting heavy objects or to change the direction of applied forces for various means. A pulley is a very simple tool that consists of a wheel on a fixed axle that has grooves for keeping a rope or wire in place. This makes pulleys useful for lifting heavy objects using applied human force.Full Answer >
