Introduction The Mechanical Advantage Of A Moveable Pulley Is Equal To The Number Of Ropes That Support The Moveable Pulley. (When Calculating The Mechanical Advantage Of A Moveable Pulley, Count Each End Of The Rope As A Separate Rope). A Pulley, Which Is Derived From The Greek Word Polos, Meaning Axis, Is A Wheel With A Groove. The Pulley Is A Simple Machine, Consisting Of A Wheel That Rotates Around A Stationary Axle. The Outer Rim Of The Pulley Is Grooved To Accommodate A Rope, Chain, Belt, Or Cable. Pulleys Are Used For Lifting By Attaching One End Of The Rope To The Object, Threading The Rope Through The Pulley (Or System Of Pulleys), And Pulling On The Other End Of The Rope. A Single, Fixed Pulley Just Changes The Direction Of The Applied Force And Make It Easier To Lift The Load, Since A Person Can Pull Down On A Rope, Rather Than Simply Lifting The Load. The Greater The Number Of Pulleys In The System, The Less Force It Will Take To Lift An Object. The Pulley Makes Lifting The Boulder Easier Because It Reduces The Effort Required To Lift. But Notice That, Although Lifting Becomes Easier, You Pull A Rope That Travels A Greater Distance Than The Height To Which You Lift The Boulder. This Extra Distance Decreases Your Effort By Giving You A Mechanical Advantage. The Mechanical Advantage Of A Moveable Pulley Is Equal To The Number Of Ropes That Support The Moveable Pulley. (When Calculating The Mechanical Advantage Of A Moveable Pulley, Count Each End Of The Rope As A Separate Rope).
