What are pulleys used for?

Answer 1

Eg volkswagon has a timing belt and a pulley tensioner that make the car run if they go your car won't work. They are supposed to be replaces every 100000km and when you replace one you replace both of them along with the watercpump because the labour is expensive and you don't want to have to pay to do it again in a month

a mechanical advantage as far as lifting

a pulley is use to lift loads, apply forces, and transmit power.
to make work easier and to lift thing heavier than you and moveable pulleys are used the zipline and cloths lines but what in comes done to is it is a simple machine.

you use a pulley to lift a car engine
A pulley can be used in a number of ways. The most common use of a pulley, however, is when one needs to lift large, heavy objects, usually with a truck or other large vehicle.
the uses of pulley is to carry things above and below and to make distribution of things easier.
Pulleys afford a mechanical advantage in, for example, the lifting of heavy or awkward loads to various heights. While pulleys are not particularly efficient (energy is lost to friction, and the pulleys and cables/ropes add their own weight to the load lifted), they allow the application of a lesser force over a greater distance.

The effect of a pulley is analogous to the gears of a bicycle; a lower gear makes it easier to turn the pedals, but they must be turned more often for the bicycle to travel the same distance. Likewise, a pulley system makes it easier to lift a load, but the length of cable used to lift the load is greater than the distance the load is lifted. The more pulleys that are used, the easier it is to lift the load, but the longer the length of cable needed to lift the the same distance.

Examples of pulley usage in the real world include:

- lifting heavy machinery, materials, and tools to heights at building sites.

- hoisting patients between a bed and wheelchair using a sling attached to pulleys, allowing the task to be undertaken by a single person.
what
pulley is made of picking something up
A pulley is a big wheel. It is easier to pull a rope down that to lift something up. Thus, it is easy to attach a rope to a heavy object and throw the rope around the pulley. Then you pull down on the rope. The heavy object goes up.
It is used to pull things up or down
The pulley is currently used to easily lift items and objects.

pulleys can be used for many things, such as elevators, garage doors, cranes etc.I think that a pulley is use for many things in the world.
