Its main span collapsed into the Tacoma Narrows four months later on November 7, 1940, at 11:00 a.m. Tacoma Narrows Bridge may have collapsed because of resonance. Storm winds are said to have resonated with the natural frequency of the bridge. This caused the amplitude of the bridge's sway to increase until the bridge collapsed.]]> 2018-02-27 15:16:35 UTC https://padlet.com/hannah_sunde/zwyzk8g536yh/wish/235921769 Picture hannah_sunde https://padlet.com/hannah_sunde/zwyzk8g536yh/wish/235925730 2018-02-27 15:21:25 UTC https://padlet.com/hannah_sunde/zwyzk8g536yh/wish/235925730 Picture hannah_sunde https://padlet.com/hannah_sunde/zwyzk8g536yh/wish/235926583 2018-02-27 15:22:34 UTC https://padlet.com/hannah_sunde/zwyzk8g536yh/wish/235926583
