This assignment is inspired by the Millennium Bridge in London, England. The Millennium Bridge is a suspension bridge for pedestrians only. Many visitors walked across the bridge in the first day of its opening in 2000. However, these visitors were treated to something unusual. They noticed that, when there were many people on the bridge, the bridge started to sway a lot. You can watch the wobbling of the bridge in this YouTube video. Since the bridge did not sway much if there were few people on the bridge, the authority decided to limit the number of people on the bridge. Eventually, the bridge was closed a few days after its opening. The bridge was re-opened after additional dampers have been put on the bridge, see  for a report on how the bridge was stabilised.
