Archimedes is credited by Plutrarch with designing the first block and tackle pulley.
Archmedes is actually spelled like Archimedes he is a person who creates stuff i am so awesome love Melissa Charles

Archimedes was a great mathematician.
There are fixed, moveable, and compound pulleys.
Movable pulley is attache to the object you are moving while Fixed Pulley changes direction of the applied force.LaDy_caRoLi "Christine carren alcantara"
It is a wheel with a rope moving grove around it
In a pulley system in equilibrium, the forces acting on the pulley must be balanced. This means that the tension in the rope pulling on each side of the pulley is equal, resulting in a state where the pulley is not moving. This equilibrium condition is reached when the net force acting on the pulley is zero.
A guide pulley helps to change the direction of a moving belt or cable, while a tension pulley is used to maintain the proper tension in the belt or cable.
A pulley overcomes static friction, which is the friction between the surface of the pulley and the rope or belt moving over it. This allows the pulley to rotate smoothly and lift objects with less force required.
The bicycle is not a simple machine, there are too many interacting moving parts.
Archimedes discovered/identified the lever, the pulley, and the screw as simple machines.
