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

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.
assuming that your question is what jobs are pulleys used for... then the answer is any job that you need to lift something that is heavy. The pulley give a mechanical advantage when used together with other pulleys to apply more force to move the object
yes the do have pulleys
Many people use pulleys in their jobs. The rides like Supreme scream, which go vertically up and down have pulleys in them. Elevators have pulleys in them, and people who ship cargo use pulleys in their cranes.
Archimedes (not a group, a guy) invented pulleys as well as other simple machines.
The Giza Pyramids were constructed using step-walking wooden four-lobe pinion-pulleys with a mechanical advantage of 2.8 (MA=2.8) This ancient pulley was unknown to the modern world until 27 August 2006. The design and operation of this pulley is nothing like any pulley known in the modern world. Google four lobe pinion pulley.

When two or more pulleys are used together it is called a compound pulley system.
pulleys are actually still used in elevators, cranes, and car lifts. however, they're used with motors.
The pulley was used by the Romans to move large pieces of equipment and to create buildings. Pulleys were also used in the creation of weapons.
pulleys are used in everyday life in many different situations and mechanisms. This is understandable because pulleys when used and set up correctly can lift or move a weight that is much greater than the force exerted upon the pulley. they are used in crane systems.
Pulleys have a rope that goes over the top of the pulley that is when pulled used to raise what ever you want raised.
Pulleys are used in manual wells for drawing water from wells in a bucket. Drum-style pulleys are found in the rotating brush in an upright vacuum cleaner.
Movable pully
For taking out water from wells.
Pulleys are used to lift objects
Pulling gears, pulleys and such.
