A system of pulleys is called a block and tackle
A crane is a lifting machine, generally equipped with a Winder(also called a wire rope drum), Wire_ropeor Chainand Sheave_(mechanical), that can be used both to lift and lower materials and to move them horizontally.

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.
yes car engines are pulleys
idk but pulleys were made in Sicily 250 B.C
When two or more pulleys are used together it is called a compound pulley system.
block and tackle.
When two pulleys work together, it is called a pulley system or a block and tackle system. This arrangement allows for mechanical advantage by distributing the load between the two pulleys, making it easier to lift heavy objects.

Yes, the belt system has pulleys.
There are a total of three pulleys in the system.
The pulley formula used to calculate the mechanical advantage of a system involving pulleys is MA 2n, where MA is the mechanical advantage and n is the number of pulleys in the system.
Not entirely sure what you mean but maybe this will help: In general the more pulleys you have in your system the less force you will need to apply to lift a certain load, in this case the system of pulleys is generally called a "block and tackle".
Pulleys in a flagpole system help to make raising and lowering the flag easier by distributing the force required. The pulley system allows for the flag to be hoisted and lowered with less effort as the weight is distributed between multiple ropes and pulleys. The more pulleys used, the easier it is to operate the flagpole system.
