How is a wheel and axle made?

The simple machine called a wheel and axle refers to the assembly formed by two disks, or cylinders, of different diameters mounted so they rotate together around the same axis. The thin rod which needs to be turned is called the axle and the wider object fixed to the axle, on which we apply force is called the wheel.

Why is axle so important?

Axles are used for steering, driving, and braking, meaning they are important for basically every aspect of vehicle use. Essentially, the axles transfer power and torque from your engine to your wheels.

How do wheel and axle make life easier?

The wheel and axle is a simple machine that reduces the friction involved in moving an object, making the object easier to transport. When an object is pushed, the force of friction must be overcome to start it moving. Once the object is moving, the force of friction opposes the force exerted on the object.

How does a wheel work?

Wheels bolt to the wheel hub and rotate around the axles. Power is transferred from the axle/hub to the tires, providing the leverage needed to move the car. Besides looks, changing your car's wheels can have a significant impact on wheel alignment, handling, braking, ride quality, and acceleration.
