What Is A Wheel And Axle?
One type of simple machine is a wheel and axle. A wheel and an axle are always together because a wheel needs an axle to spin. A fan is a type of simple machine because the blades of a fan (wheel) spin on a rod (axle). A wheel isn't really a simple machine without an axle. Wheels and axles are awesome.
