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.
Pulleys could be used in medieval times in the drawbridge, a mill or other medieval mechanics.
Yes.
Four lobe pinion 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.
The Egyptians didn't use camels they feared them and the camel lived in the desert & the egyptians feared the desert aswell
Not necessarily. Some fans use belts on pulleys to transfer the rotary motion of the motor to the fan blade, while others use gears, and some are direct drive.

The ancient Egyptians writing is called: Hieroglyphics.
The ancient Egyptians in this period, it is thought, never had pulleys. They most likely used inclined planes, ramps made from rubble mixed with clay to raise the block to the desired level. The blocks themselves were placed on sledges and dragged up the ramp by gangs of slaves. The bigger the block the more slaves it took. The blocks were put in their final position by the use of levers and brute force.
at the rock climbing place they use pulleys to keep you safe :D
tape, flagpoles, those things you use for rock climbing, and the pulleys the construction people use! :)

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.
Egyptians still use hieroglypics
To pulled things up
PULLEYS
to hoist water.
This depends on their intended use.
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.
