The term GEAR ELEMENTS can be summarized as the components of a gear system, which includes COGS, also known as cogwheels or gearwheels. COGS are the most basic elements of a gear system, and they are used to transmit rotational motion between two shafts. They are usually made of metal and have teeth that interlock with each other to create a mechanical connection. COGS are essential for the functioning of many machines, such as bicycles, clocks, and automobiles.
