The wheel and axle is a very efficient machine, and it can be used to lift heavy objects or to change the direction of a force. Some common examples of wheel and axle systems include:
* A doorknob
* A car wheel
* A bicycle wheel
* A pulley
Here is a more detailed explanation of how a wheel and axle works:
1. When a force is applied to the wheel, it causes the wheel to rotate.
2. The rotation of the wheel causes the axle to rotate.
3. The axle is attached to the object that is being lifted or moved.
4. As the axle rotates, it causes the object to lift or move.
The amount of force required to turn the wheel is inversely proportional to the radius of the wheel. This means that the larger the wheel, the less force is required to turn it.
