Failure of the original Tacoma Narrows Bridge

The badly visible, adroit agee that resulted in the 1940 collapse of "Galloping Gertie," the aboriginal Tacoma Narrows Bridge, has sometimes been characterized in physics textbooks as a classical archetype of resonance. However, this description is misleading. The adverse accordance that destroyed the arch were not due to simple automated resonance, but to a added complicated alternation amid the arch and the apprehension casual through it — a abnormality accepted as aeroelastic flutter. Robert H. Scanlan, ancestor of arch aerodynamics, has accounting an commodity about this misunderstanding.15
