The wheel is probably the most impo

The wheel is probably the most important mechanical invention of all time. Nearly every machine built since the beginning of the Industrial Revolution involves a single, basic principle embodied in one of mankind’s truly significant inventions. It’s hard to imagine any mechanized system that would be possible without the wheel or the idea of a symmetrical component moving in a circular motion on an axis. From tiny watch gears to automobiles, jet engines and computer disk drives, the principle is the same.Photo courtesy www.ohm.com

Based on diagrams on ancient clay tablets, the earliest known use of this essential invention was a potter’s wheel that was used at Ur in Mesopotamia (part of modern day Iraq} as early as 3500 BC. The first use of the wheel for transportation was probably on Mesopotamian chariots in 3200 BC. It is interesting to note that wheels may have had industrial or manufacturing applications before they were used on vehicles.
A wheel with spokes first appeared on Egyptian chariots around 2000 BC, and wheels seem to have developed in Europe by 1400 BC without any influence from the Middle East. Because the idea of the wheel appears so simple, it’s easy to assume that the wheel would have simply "happened" in every culture when it reached a particular level of sophistication. However, this is not the case. The great Inca, Aztec and Maya civilizations reached an extremely high level of development, yet they never used the wheel. In fact, there is no evidence that the use of the wheel existed among native people anywhere in the Western Hemisphere until well after contact with Europeans.
Even in Europe, the wheel evolved little until the beginning of the nineteenth century. However, with the coming of the Industrial Revolution the wheel became the central component of technology, and came to be used in thousands of ways in countless different mechanisms.

Die wiel é waarskynlik morrer belangrikste meganiese uitvinding van alle tye. Byna Elke masjien wat sedert morrem começam a van morrer Industriële Revolusie behels 'n enkele, basiese beginsel Vervat em een van baie belangrike uitvindings mensdom se. Dit é moeilik om' n gemeganiseerde stelsel wat sonder morrer wiel de morrer idee van 'n simmetriese komponent beweeg em' n Sirkel op Beweging 'n como moontlik sou wees Dink. motores om horlosie ratte van Klein, enjins jato en skyfaandrywers rekenaar, morrem beginsel é morrer same.Photo www.ohm vergunning. com op grond van diagrama op antieke kleitablette, morrem vroegste bekende gebruik van hierdie noodsaaklike uitvinding foi wiel 'n pottebakker wat gebruik por Ur em Mesopotamie (deel van morrer hedendaagse Irak} para Vroeg como 3500 vC. morrem eerste gebruik van die wiel vir vervoer foi waarskynlik op waens Mesopotamiese em 3200 CV. Dit é interessant om daarop te deixar dat industriële wiele de vervaardiging aansoeke voordat HULLE mag gehad het gebruik op voertuie.

Omdat die idee van die wiel verskyn tão eenvoudig nie, dit é maklik om te aanvaar dat die wiel sal net "gebeur" em Elke Cultura Ciência wanneer dit 'n bepaalde vlak van sofistikasie bereik het. dit é egter nie die Geval nie. morrer Groot Inca, Asteca en Maya beskawings bereik 'n baie enxada vlak van ontwikkeling, maar HULLE het nooit gebruik die wiel. Trouens, daar está geen bewyse dat die gebruik van die wiel bestaan ​​onder inheemse mense oral em die tot goed Westelike Halfrond ná kontak conheceu Europeërs. Selfs em Europa, morrem wiel ontwikkel bietjie tot aan die começar van morrer eeu negentiende. Maar conheceu die KOMS van morrer Industriële Revolusie die wiel é morrer sentrale komponent van tegnologie, en het om gebruik te palavra em duisende manière talle verskillende meganismes.
