Not every finished product resembles the blueprint it was based on. Sometimes mistakes are made. Sometimes plans have to be changed. Often, an engineer will finish creating something only to realize that there’s a big problem with their design - one that they never thought of before they started building! Sometimes a mistake like this will doom a construction project completely, but other times they’ll turn out to be happy little accidents - like all the incredible engineering calculations you’re about to see in this video!
