Archimedes (not a group, a guy) invented pulleys as well as other simple machines.
idk but pulleys were made in Sicily 250 B.C
In acient greece
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.
Pulleys have been used for thousands of years by many different civilisations. It is impossible to say who first invented them or where.
He made it because it took half the weight of the load off
Archimedes discovered the concept of gravity with his levers and pulleys, his theory of displacement and invented the screw.
Pulleys and levers have been used in various forms for centuries, with evidence of their use dating back to ancient times. The precise origins are unclear, but they were likely developed independently by different ancient civilizations for tasks such as construction, transportation, and agriculture. The principles behind pulleys and levers have been refined and applied in numerous inventions since then.
There are three main types of pulleys: fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are attached to a stationary object, movable pulleys move with the load, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.
yes the do have pulleys
FIXED PULLEYMOVABLE PULLEYBLOCK AND TACKLEAdditonal answerFlat pulleys, v-pulleys, multi-V pulleys, jockey pulleys
The three types of pulleys are fixed pulleys, movable (or movable) pulleys, and compound pulleys. Fixed pulleys change the direction of the force applied, movable pulleys provide a mechanical advantage by reducing the force needed, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.
