What happens when you change the size of the wheels in a gear system?

Changing the size of the wheels in a gear system alters the gear ratiOS, which affects the torque and speed of the output. Larger wheels generally increase torque but decrease speed, while smaller wheels do the opposite. This adjustment can impact the overall efficiency and performance of the system, depending on the intended application. Additionally, it may require recalibrating other components to ensure optimal functionality.
