A cogwheel system based on simple physics theories #249789624
Description
A gear (also called a cogwheel) is a type of simple machine that is used to manipulate the magnitude or direction of a force. Gears are used in combination and are linked together by their teeth - referred to as cogs - in order to form a "gear train". These gear trains are useful for transferring energy from one part of a system to another. Systems that utilize gears and gear trains include
