Structures can transform from stable to unstable under hidden forces. Resonance starts when external forces match a structure's natural frequency, causing dangerous oscillations. At the Tacoma Narrows Bridge, steel cables and girders twist and oscillate violently as aeroelastic flutter surges uncontrollably. The bridge’s motion rises until it collapses under the stress of continuous oscillations beyond its design limit. On the Millennium Bridge, synchronized footfalls pull the structure into lateral waves, shifting it up to 7 centimeters side to side. This lateral swaying creates pressure that tightens connections and stresses supports, making the bridge unsafe for humans. Follow for one real science fact every day.
