The ratio between the rotation velocities of the pulleys, the gear ratio, is the same as in friction drives
Uses: in industrial machines, car engines, washing machines, dulls
Moveable pulleys
-
The effort needed to move a load with a
moveable pulley is half of the effort needed
with a fixed pulley
Fixed pulleys
A fixed pulley is a wheel that has a channel groove for a rope, cham or belt to go round it.
A fixed pulley is balanced when the effort, F, is equal to the load. R: F= R

Compound pulleys
This is a set of fixed and moveable pulleys, often called a block and tackle. If we use more pulleys it becomes more complex, but less effort
is needed to move the load
