This came about not simply as a result of mechanical resonance, but also aeroelastic flutter – a process that occurs when complex, varying oscillations are caused by passing winds. One of the most famous examples of a resonance disaster is the 1940 Tacoma Narrows Bridge collapse in Washington, USA. When this stored energy exceeds an object’s load limit, it will lose structural integrity. If these vibrations happen to occur at a system’s resonance frequency, then oscillation generates excitation at an atomic level, where more and more energy is stored. In other words, this means that if a structure begins to vibrate in a violent manner, it’s liable to fail mechanically and this can quickly lead to its total destruction.
This is the susceptibility of a structure to respond at an increased amplitude when the frequency of its oscillations matches its natural frequency of vibration. 👉 Many bridges and buildings have fallen down due to the effects of resonance – or to be more precise, mechanical resonance.
