Pulleys are categorized as a type of simple machine consisting of a grooved wheel and a rope or cable. These devices help us to lift heavy loads in an effective manner, as well suspend various objects in the air (for example: a flag). Read this ScienceStruck article to know more about the various types of pulley systems and their working mechanisms.
Pulleys are one of the six simple machines. The other simple machines are the wheel and axle, the inclined plane, the wedge, the screw, and the lever. A machine is a tool used to make work easier, and the six simple machines were some of mankind''s .
One or more independently rotating pulleys can be used to gain mechanical advantage, especially for lifting weights. The shafts about which the pulleys turn may affix them to frames or blocks, and a combination of pulleys, blocks, and rope or other flexible material is referred to as a block and tackle.
Two pulleys can be used to create a simple belt and pulley system, in which a belt is looped between the two pulleys. One pulley is the "driving pulley", and as it spins, it transmits power through the belt either via friction or teeth, thus spinning a "driven .
