Tree trimming uses combination pulleys. Also combination pulleys are used to lift engines out of cars to work on them. Some construction sites use them in places they cannot get a crane.
This depends on their intended use.
yes car engines are pulleys
A system of pulleys is called a block and tackle
idk but pulleys were made in Sicily 250 B.C
yes, pulley will help IF not the if YOU USE COMBINE TWO OR MORE PULLEYS. Yes, using a pulley or a system of pulleys will reduce the force needed to lift a brick (or anything). HOWEVER the distance that the rope (or whatever effects the pulley system) has to now travel further so that the energy required to lift the brick through an equal height is always the same.
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.
at the rock climbing place they use pulleys to keep you safe :D
No, zip lines are not an example of movable pulleys. Zip lines use a combination of gravity and mechanical devices to transport riders from one point to another, but they do not incorporate pulleys in the same way that other systems, such as flagpoles or blinds, do.
tape, flagpoles, those things you use for rock climbing, and the pulleys the construction people use! :)
No
a combination of one or more fixed pulleys and one or more movable pulleys such as a crane
a combination of one or more fixed pulleys and one or more movable pulleys such as a crane
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
Gym pulleys Window blinds elevator pulleys garage door pulleys
To pulled things up
This depends on their intended use.
