007skaty Playground Swing Resonance
Shift your weight / Double the beat / Touch the sky
007skaty On November 7, 1940, Washington State's bridge collapsed when periodic wind forces triggered a destructive phenomenon called aeroelastic
007skaty Two chrome tuning forks on glass resonators transfer sound waves through the air.
007skaty Time the swings of each resonator to learn how matching frequencies transfer energy.
Bridge vibrations: The Tacoma Narrows Bridge collapsed in 1940 because moderate winds matched its natural vibration frequency [3].
What happens when two tuning forks share the exact same natural frequency and one is struck?
What is the term for the frequency at which an object naturally vibrates when disturbed?
Who first documented pendulum motions in 1602, helping lay the groundwork for resonance?
What did Hermann von Helmholtz use to isolate specific audio frequencies in the 1850s?
In what year did the Tacoma Narrows Bridge collapse due to wind-induced resonance?
What physical phenomenon occurs when an external force matches an object's natural frequency?
