Samsonite Luggage 22 Inch Andante Wheeled Duffel - One of the wheels is a circular component that is intended to rotate upon an axle bearing. The wheel is one of many reasons pieces of the wheel and axle which is about the six simple machines. Wheels, with axles, allow heavy objects that they are moved easily facilitating movement or transportation while supporting a lot, or performing labor in machines. Wheels are also used by other purposes, including a ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are only in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together by using axles. To ensure wheels to rotate, a short while has to be applied to the wheel about its axis, either via gravity or by the application 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 extended variety of the root *kwel- "to revolve, move around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, link units both meaning "circle" or "wheel ".Precursors of wheels, identified as "tournettes" or "slow wheels", were known with the Middle East via the 5th millennium BCE (one of the earliest examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). We were holding made from stone or clay and secured to the ground by having a peg inside center, but required effort to turn. True (freely-spinning) potter's wheels were apparently being used in Mesopotamia by 3500 BCE and possibly around 4000 BCE, as well as the oldest surviving example, that wasthat's included in Ur (modern day Iraq), dates to approximately 3100 BCE.

The pioneer proof wheeled vehicles appears with the lover of your 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), therefore question of which culture originally invented the wheeled vehicle remains unsolved.The primary well-dated depiction of an wheeled vehicle (here a wagon — four wheels, two axles) is over 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 model of wagon construction (the wheel and axle rotate together, that is to say Ljubljana Marshes Wheel), and this of one's Baden culture in Hungary (axle isn't going to rotate). They are dated to c. 3200–3000 BCE.In China, the wheel was certainly present considering the adoption of this chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
