Con­struc­tion at the Tow­er of Pisa first started within the 12 months 1173. Through 1178, the archi­tects knew that they had a prob­lem on their palms. Constructed on an unsteady foun­da­tion, the tow­er started to sink underneath its personal weight and shortly get started­ed to lean. Medieval archi­tects attempted to handle the lean. How­ev­er, it consistent with­sist­ed and incre­males­tal­ly wors­ened over the following 8 cen­turies. Then, in 1990, Ital­ian writer­i­ties closed the tow­er to the pub­lic, concern­ing it will col­lapse. For the following 11 years, engi­neers labored to sta­bi­lize the struc­ture. How did they put the tow­er on a gamble­ter foot­ing, because it have been, whilst nonetheless pre­serv­ing a few of its icon­ic lean? That’s the sub­ject of this intrigu­ing video by means of the YouTube chan­nel Prac­ti­cal Engi­neer­ing. Watch it above.
