Step-by-step explanation:
Ferris wheel (also called a Giant Wheel or an observation wheel) is an amusement ride consisting of a rotating upright wheel with multiple passenger-carrying components (commonly referred to as passenger cars, cabins, tubs, gondolas, capsules, or pods) attached to the rim in such a way that as the wheel turns, they are kept upright, usually by gravity. Some of the largest modern Ferris wheels have cars mounted on the outside of the rim, with electric motors to independently rotate each car to keep it upright. These cars are often referred to as capsules or pods.

Ain Dubai. The largest Ferris Wheel in the world
The original Ferris Wheel was designed and constructed by George Washington Gale Ferris Jr. as a landmark for the 1893 World's Columbian Exposition in Chicago; however, wheels of this form predate Ferris's wheel by centuries. The generic term "Ferris wheel," now used in English for all such structures, has become the most common type of amusement ride at state fairs in the United States.[1]
The tallest Ferris wheel, the 260-metre (853 ft) Ain Dubai in the United Arab Emirates, opened in October 2021. The previous record holder since 2014 had been the 167.6-metre (550 ft) High Roller in Las Vegas, Nevada, which opened to the public in March 2014.
Terminology and designEdit
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.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".[4]
Design variation includes 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.

"Pleasure wheels", whose passengers rode in chairs suspended from large wooden rings turned by strong men, may have originated in 17th-century Bulgaria.[1][5]
The Travels of Peter Mundy in Europe and Asia, 1608–1667[6] describes and illustrates "severall Sorts of Swinginge used in their Publique rejoyceings att their Feast of Biram" on 17 May 1620 at Philippopolis (now Plovdiv) in the Ottoman Balkans.[5] Among means "lesse dangerous and troublesome" was one:
like a Craine wheele att Customhowse Key and turned in that Manner, whereon Children sitt on little seats hunge round about in severall parts thereof, And though it turne right upp and downe, and that the Children are sometymes on the upper part of the wheele, and sometymes on the lower, yett they alwaies sitt upright.
Five years earlier, in 1615, Pietro Della Valle, a Roman traveller who sent letters from Constantinople, Persia, and India, attended a Ramadan festival in Constantinople. He describes the fireworks, floats, and great swings, then comments on riding the Great Wheel:[7]
I was delighted to find myself swept upwards and downwards at such speed. But the wheel turned round so rapidly that a Greek who was sitting near me couldn't bear it any longer, and shouted out "soni! soni!" (enough! enough!)
Similar wheels also appeared in England in the 17th century, and subsequently elsewhere around the world, including India, Romania, and Siberia.[5]
A Frenchman, Antonio Manguino, introduced the idea to America in 1848, when he constructed a wooden pleasure wheel to attract visitors to his start-up fair in Walton Spring, Georgia.
