Critical Frequency - Tacoma Narrows Bridge Collapse






Here is a short documentary on the Tacoma Narrows Bridge (courtesy of YouTube). It is very interesting to see how the critical frequency can play a role in design. The bridge suffered a collapse when steady winds at the critical frequency caused the bridge to oscillate up and down before ultimately destroying it. As in class, whenever an object is being oscillated at the critical frequency, the oscillations keep getting larger and larger. Just thought it might be interesting since it covers the same topics as we have been covering in lecture.
