The original type of spoked wheel with wooden spokes was used for horse-drawn carriages and wagons. In early motor cars, wooden spoked wheels of the artillery type were normally used. In a simple wooden wheel, a load on the hub causes the wheel rim to flatten slightly against the ground as the lowermost wooden spoke shortens and compresses.
It accounts for the "wagon-wheel effect", so-called because in video, spoked wheels (such as on horse-drawn wagons) sometimes appear to be turning backwards. A strobe fountain, a stream of water droplets falling at regular intervals lit with a strobe light , is an example of the stroboscopic effect being applied to a cyclic motion that is not ...
Wire spokes are under tension, not compression, making it possible for the wheel to be both stiff and light. Early radially-spoked wire wheels gave rise to tangentially-spoked wire wheels, which were widely used on cars into the late 20th century. Cast alloy wheels are now more commonly used; forged alloy wheels are used when weight is critical.
Wire wheels, wire-spoked wheels, tension-spoked wheels, or "suspension" wheels are wheels whose rims connect to their hubs by wire spokes. [ 1 ] [ 2 ] [ 3 ] Although these wires are considerably stiffer than a similar diameter wire rope , they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting ...
Ratha (Proto-Indo-Iranian: *Hrátʰas, Vedic Sanskrit: रथ, IAST: rátha; Avestan: raθa) is the Indo-Iranian term for a spoked-wheel chariot. The term has been used since antiquity for both fast chariots and other wheeled vehicles pulled by animals or humans, in particular the large temple cars or processional carts still used in Indian ...

The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...
