Gears

Gears are toothed wheels that work together to transmit torque and rotational motion between mechanical parts. When one gear rotates, its teeth push against those of a neighboring gear, causing it to turn as well. Gears can change the direction of movement, increase or decrease speed, and modify force within a machine. They are fundamental in devices like clocks, vehicles, and industrial machinery, enabling precise control of motion and power transfer. Gears come in various shapes and sizes, designed to suit specific mechanical needs and improve efficiency in transmitting energy.
