The wheel
The wheel has been an essential part of human life from the
very early years of human civilization. The wheel can be best described as a
circular object that rotates on an axial bearing. The earliest wheels were known to be wooden
disks with a hole in the middle for the axle.
The word wheel first came from an Old English word. In Sanskrit, the wheel is called chakra to
mean round or circle. It is believed
that the wheel first originated around 3500 BC in Mesopotamia (part of
modern-day Iraq) where it was used for chariots. Some argue that it was invented by the Mesopotamians,
the Northern Caucasus and Central Europeans.
Therefore, the issue of where the wheel originated in still remains a
mystery.
