Which technician correctly describes the function of a differential?

The function of a differential is crucial in a vehicle's drivetrain, as it allows the wheels to rotate at different speeds, particularly when turning. This helps maintain traction and ensures a smooth, stable ride. The differential accomplishes this by distributing engine power to the wheels while compensating for the differing distances each wheel travels during a turn.

Technician B likely provides the correct description of this function, emphasizing how the differential enables the outer wheel to rotate faster than the inner wheel during a turn. This is essential for effective handling and stability in a vehicle. The understanding of this role is fundamental for technicians, as it relates directly to vehicle dynamics and safety.

In contrast, other descriptions may mischaracterize the differential's role or overlook its importance in managing wheel speed differences, which can lead to inadequate maintenance or repairs. Thus, the correct identification of Technician B can reflect a deeper understanding of differential operation and its significance in manual transmission systems.
