3D Legend
The red car has one hinge for the rear wheels. This means that when going round corners, the outside wheel is dragged along because it needs to cover a longer distance. The Blue car has a series of gears called a differential. This allows power to be transferred evenly between the rear wheels and allow them to spin at differnt speeds for smoother steering. Notice how I used exactly 4 hinges to power that green object. This is because of the gear reductions used in the differential makes the green gear want to spin alot more to turn the white ones once. If one hinge was used, then the rear wheels would not produce enough torque for forward motion.
