A gear system is a mechanical arrangement of rotating gears that transmit power and motion between different components of a machine or mechanism. It uses interlocking teeth on the gears to transfer torque, allowing for speed and direction changes in a controlled manner. The ⚙️🔧 symbol represents the essence of a gear system, with the gears denoted by the gear emoji (⚙️) and the wrench emoji (🔧) signifying the maintenance and adjustment involved in working with gears.
