The wheel is everywhere on all our cars, trains, planes, machines, wagons, and most factory and farm equipment. What could we move without wheels? But as important as the wheel is as an invention, we don't know who exactly made the first wheel. A wheel is a device that allows heavy objects to be moved easily through rotating on an axle through its center, facilitating movement or transportation while supporting a load, or performing labor in machines. Common examples found in transport applications. A wheel, together with an axle, overcomes friction by facilitating motion by rolling. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity, or by application of another external force. More generally the term is also used for other circular objects that rotate or turn.
Wheels are very important chapter in human history and development. Wheels have very symbolic importance in all the cultures or religions or nations. We have our own national flag with Ashok Chakra in the centre. So wheels are most important invention made by humans. Wheels brought the world closer and made humans life easy. Today we can’t imagine our lives without wheels.
