How differential principle increase velocity ratio in differential axle?

The differential principle increases the velocity ratio in a differential axle by allowing the wheels on either side of the axle to rotate at different speeds while still receiving power from the engine. This is achieved through a system of gears and shafts within the differential mechanism that distribute torque to each wheel independently. By enabling the wheels to rotate at different speeds, the differential principle enhances traction, stability, and maneuverability, especially when navigating corners or uneven terrain.
