The wheel is one of the primary aspects of the wheel and axle which is just about the six simple machines.

Wheels can also be used in other purposes, maybe a ship's wheel, controls, potter's wheel and flywheel.Common examples are located in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together with the aid of axles. In order for wheels to rotate, a short while really should apply to the wheel about its axis, either as a result of gravity or by use of another external force or torque.The English word wheel is from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, a long form of the cause *kwel- "to revolve, move ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, these both meaning "circle" or "wheel ".Precursors of wheels, often known as "tournettes" or "slow wheels", were known around the Middle East by your 5th millennium BCE (one of the initial examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).
