17 Inch Steel Wheels - A wheel is often a circular component that is intended to rotate on an axle bearing. The wheel is needs . components of the wheel and axle which has become the six simple machines. Wheels, along with axles, allow heavy objects to become moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels may also be intended for other purposes, perhaps ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are simply in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together through axles. So that wheels to rotate, some time must have to be relevant to the wheel about its axis, either by gravity or by the employment of another external force or torque.The English word wheel is produced by the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, an expanded variety of the generator *kwel- "to revolve, move around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, ppos both meaning "circle" or "wheel ".Precursors of wheels, referred to as "tournettes" or "slow wheels", were known from the Middle East through the 5th millennium BCE (one of the primary examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). We were holding produced from stone or clay and secured down having a peg in the center, but required effort to turn. True (freely-spinning) potter's wheels were apparently employed in Mesopotamia by 3500 BCE and perhaps as soon as 4000 BCE, as well as the oldest surviving example, that had been included in Ur (modern day Iraq), dates to approximately 3100 BCE.

The best proof of wheeled vehicles appears while in the second half within the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), to be sure the question which culture originally invented the wheeled vehicle continues to be unsolved.The initial well-dated depiction of any wheeled vehicle (here a wagon — four wheels, two axles) is about the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated inside a Funnelbeaker culture settlement in southern Poland.The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia (Ljubljana Marshes Wooden Wheel) currently is dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.Two types of early Neolithic European wheel and axle are known; a circumalpine form of wagon construction (the wheel and axle rotate together, like Ljubljana Marshes Wheel), and that with the Baden culture in Hungary (axle would not rotate). They are dated to c. 3200–3000 BCE.In China, the wheel was certainly present using the adoption within the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
