to gain mechanical advantage. So you dont need to apply as much force to move something.
A pulley halves the ammount of force needed, but you need to pull a rope twice as far to move the object the same distance.
The pulley was invented around 1500 BCE in Mesopotamia. It was used to make lifting heavy objects easier by distributing the weight and allowing for more control.
The compound pulley system was invented by Archimedes, an ancient Greek mathematician, around the 3rd century BC. Archimedes is also known for his contributions to geometry, physics, and engineering.
Pulleys were first made out of wood, stone, or metal when they were first invented. These materials were used to create the wheel and the axle necessary for the pulley mechanism to function.
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
the pulley was invented in the 1956
The simple pulley was invented in ancient times by an unknown person. The compound pulley was invented by Archimedes.
maybe the pulley but not the lever he invented the pulley but not the lever
Archimedes
Archimedes
very early times
yes they did they did i have a history degree. Sorry but the first pulley was not invented by the Egyptians it was invented by Archimedes of Syracuse in around 250 BCE.

It could be used to pull ships onto land and to get water from a well. Archimedes invented the compound pulley in ancient Greece.
Archimedes invented the six simple machines.
