What does the wheel and axle do on a clock?

The wheel and axle in a clock work together to regulate the movement of the clock's hands. The wheel, often connected to the gear train, turns around the axle, which helps convert the energy from the clock's power source, such as a spring or weight, into controlled rotational motion. This mechanism ensures that the hands move at a consistent speed, allowing for accurate timekeeping. Additionally, the interaction between the wheel and axle contributes to the overall gear ratio, affecting how quickly the hands advance.
