Sheave vs Pulley
Pulleys have been around for a long time to lift a heavy load easier via the system of ropes and wheels. SHEAVE and PULLEY are sometimes used interchangeably, but technically they are not the same.
SHEAVE: As a part of the pulley system, it is the rotating, grooved wheel inside the pulley. This is the part where a rope/wire fits into.
PULLEY: It is one of six types of simple machines. This is a system consisting wheel(s) over which a rope/wire can be pulled to change the direction of forces and make lifting easier. It allows loads to be lifted using much less force than would normally be applied.
