👉 A pulley is a mechanism that allows a mass to be supported by two or more weights, typically connected to a central pivot. The purpose of a pulley is to allow for easier movement and distribution of weight between different parts of an object, such as wheels on a bicycle. The term "unpulleyed" refers to the fact that in a pulley system, there are no moving parts or mechanisms other than the weights connecting them. This means that the entire system is completely static
