{{Wiktionary}} [[Image:Wheel Iran.jpg|thumb|right|A spoked wheel on display at The [[National Museum of Iran]], in [[Tehran]]. The wheel is dated to the late 2nd millennium BC and was excavated at [[Choqa Zanbil]].]] [[Image:Cartwheel and axle assembly.jpg|thumb|right|The remains of a pair of [[cartwheel]]s with metal axle assembly.]] [[Image:Ox wagon at Aliwal North.jpg|thumb|right|An [[Ox-wagon]] in [[Aliwal North]], [[Eastern Cape]]. Note the three missing spokes and the metal tyre.]] A '''spoke''' is one of several [[:wikt:rod|rods]] radiating from the center of a [[wheel]] (the [[:wikt:hub|hub]] where the [[axle]] connects), connecting the hub with the round traction surface. The term originally meant the portions of a [[:wikt:log|log]] which one had split lengthwise into four or six sections. The radial members of a wagon wheel were made by carving a spoke (from a log) into their finished shape. Eventually, the term spoke was applied to the finished product of the [[wheelwright]]'s work. == Other websites == These pages are in German: *[http://www.nabendynamo.de/mont28.htm Hub dynamo assembly instructions with spoke length formula and a nice diagram] {{Webarchive|url=https://web.archive.org/web/20080224005019/http://www.nabendynamo.de/mont28.htm |date=2008-02-24 }} *[http://www.rst.mp-all.de/splaenge.htm Online spoke length calculator, uses slightly different measures than the above formula] {{Webarchive|url=https://web.archive.org/web/20150921033121/http://www.rst.mp-all.de/splaenge.htm |date=2015-09-21 }} {{Stub}} [[Category:Engineering]]
