Question

List three examples of situations where resonance is a problem, and three others where resonance is useful. In each case, state what the oscillating system is and what forces it to resonate.

Accepted Answer

Example Useful or problem? What is resonating?

Buildings in earthquake Problem Mechanical structure is forced to oscillate by energy from waves of earthquake.

Components in engines Problem At certain rates of rotation, parts of an engine may resonate mechanically; the resonance is driven by the energy output of the engine. This can lead to components cracking or disintegrating, with dangerous consequences.

Positive feedback in amplification systems (high-pitched squealing sound) Problem At certain rates of rotation, parts of an engine may resonate mechanically; the resonance is driven by the energy output of the engine. This can lead to components cracking or disintegrating, with dangerous consequences.
