What is the relationship of the input shaft compared to the output shaft?

The input shaft and output shaft are key components in a mechanical system, such as a gearbox or transmission. The input shaft transmits power from the engine or motor, while the output shaft delivers that power to the wheels or other machinery. The relationship between them typically involves a change in speed and torque, with the input shaft often rotating at a different speed than the output shaft due to gear ratiOS. This relationship is crucial for optimizing performance and efficiency in various applications.
