ETYM French poulie, perhaps of Teutonic origin.
A simple machine consisting of a wheel with a groove in which a rope can run to change the direction or point of application of a force applied to the rope; SYN. pulley-block, block.
Simple machine consisting of a fixed, grooved wheel, sometimes in a block, around which a rope or chain can be run. A simple pulley serves only to change the direction of the applied effort (as in a simple hoist for raising loads). The use of more than one pulley results in a mechanical advantage, so that a given effort can raise a heavier load.
The mechanical advantage depends on the arrangement of the pulleys. For instance, a block and tackle arrangement with three ropes supporting the load will lift it with one-third of the effort needed to lift it directly (if friction is ignored), giving a mechanical advantage of 3. + prikaži više
