|There are only two forces in the world, the sword and the spirit. In the long run, the sword will always be conquered by the spirit. - Napoleon Bonaparte|
The Tacoma Narrows Bridge Collapse
The old Tacoma Narrows Bridge, built between Tacoma and Gig Harbor, Washington in 1940, vibrated so much that it was nicknamed "Galloping Gertie." In November of 1940, just four months after it was completed, it literally whipped itself apart.

The natural frequency of the bridge setup a resonant standing wave oscillation in the structure. Unfortunately, the resonant quality or Q of the bridge was too high, meaning that it was unable to dampen the oscillations enough to avoid collapse.
