That's what happens in car steering: you turn the steering wheel (connected to a pinion) and it makes a rack shift from side to side to swivel the car's front wheels to the left or the right.nce you're back on the straight, it's a different story.

Gears are helpful in machines of all kinds, not just cars and cycles.

What is uni? Uni (oo-nee) is the Japanese name for the edible part of the Sea Urchin.
