wheel and axle: in motor and wheels to make it move
The Egyptians used the wheel and axle by transporting big stone blocks so they could build houses and pyramids.
The wheel and axle is one of six simple machines developed in ancient times and is in the category of a second- or third-class lever. In its simplest form it consists of a rod attached to a wheel so that their movements are coupled when one of the parts is turned. The wheel and axle is used either as a force multiplier (such as a doorknob, steering wheel or fishing reel) or as a distance multiplier (such as on a bicycle or the driven wheels of a car). In the first kind of application, the larger wheel is used to create more torque (in the axle) with less force.

Wheels are used for many different things. They are used for moving things, such as vehicles, wheelbarrows, tractors, and more. They are also used in pulleys, gears, and water wheels. For fun, the Wheel of Fortune uses a wheel for spinning to win prizes.
the radius of the axle and the radius of the wheel
The term axle can be confusing. On a car or a truck the term "Tandem Axle" is often used to describe a shaft itself, it's housing, or any transverse pair of wheels. The shaft rotates with the wheel which is either bolted or splined in a fixed relationship and is called an Axle or Axle housing. In an even broader sense the word Axle refers to every pair of wheels even if the wheels are not connected together. So, in that case even a pair of independent wheels, let's say, on the front or rear of a vehicle is called an axle. So, you can say a Honda Civic has 2 axles or you could say it has 4 axles and both conclusions are correct. It just depends on how you define the word axle. I personally would say it has 2 axles.
