From the perspective of civil engineering, the main reason for the collapse of the Ferris wheel in Fuzhou and Nanhu Park is that the components fall off. In fact, when building the Ferris wheel, I believe everyone has seen some steps inside, which means it has many parts. If the related button is not placed in one place, that is, at a key point, it is likely to be loose, fall off or collapse. Then, for the Ferris wheel in Fuzhou, Fujian, it collapsed for this reason.
