Ever wonder how the wheels on your car work and how they’re not slipping when you’re cornering? Back in 1937 this Chevrolet’s film explains how the automobile differential allows a vehicle to turn a corner, while keeping the wheels from skidding.

The differential allows the rear wheels to move at varying speeds. Each wheel on your car rotates on separate axles which are all mounted on a steady frame, allowing each wheel to spin independently and at differing speeds.

Spokes are attached at the end of each axle to allow the engine to control each wheel. A separate pivoted spoke is situated between the two to allow one power source to drive both wheels as the vehicle moves.

Archaeological evidence and historical claims state the possibility of differentials being used way before it was invented for vehicles. The oldest discovery so far is the Antikythera mechanism which is dated to have existed around 100BC.
