[QUOTE="IsaacVky, post: 348630, member: 12652"] Tacoma Narrows Bridge [IMG]http://www.sciencenews.org/pages/sn_arc99/1_30_99/bridge.gif[/IMG] Collapsed in year 1940 as a result of Resonance. When wind, the driving force natural frequency is almost if not identical to the natural frequency of the bridge, Resonance occurs. Resonance occurs in the engine crankshaft across the whole RPM range, be it 1500 3000 4500 or 8000. Amplitude is at its highest when damping is at its lowest. In our crank pulley case, removing the Harmonic damper resulted in increased Amplitude. [/QUOTE]
