In the ancient society, people
have invented a simple manoeuvring tool. They placed pieces
of round wood under the heavy objects and
by dragging them, heavy objects can now be moved from
one place to another. This is called the early day’s wooden
wheel transport.
Subsequently, it was discovered that
wooden wheels with larger radius can achieve faster speed
and therefore the radius of wooden
wheels kept increasing.
They slowly transformed into wheels with lever and became
the prototype of today's car model. |
