Editing Ferris wheel (section)

==Terminology and design==

The term ''Ferris wheel'' comes from the maker of one of the first examples constructed for Chicago's [[World's Columbian Exposition]] by [[George Washington Gale Ferris Jr.]] in 1893.

Modern versions have been called ''observation wheels''.<ref>[http://encarta.msn.com/encyclopedia_761588652/Ferris_Wheel.html MSN Encarta – Ferris Wheel] {{webarchive|url=https://web.archive.org/web/20090822013051/http://encarta.msn.com/encyclopedia_761588652/Ferris_Wheel.html |date=August 22, 2009 }}</ref><ref>{{cite web|url=http://web.mit.edu/invent/iow/ferris.html|archive-url=https://web.archive.org/web/20030302045005/http://web.mit.edu/invent/iow/ferris.html|url-status=dead|archive-date=March 2, 2003|title=Lemelson-MIT Program|website=web.mit.edu|access-date=October 4, 2018}}</ref> In 1892, when the incorporation papers for the Ferris Wheel Company (constructors of the original 1893 Chicago Ferris Wheel) were filed, the purpose of the company was stated as: [construction and operation of] "wheels of the Ferris or other types for the purpose of observation or amusement".<ref name="Anderson" />

Design variations include single- (cantilevered) or twin-sided support for the wheel, and whether the cars or capsules are oriented upright by gravity or by electric motors. The most prevalent design is the use of twin-sided support and gravity-oriented capsules.
