Resonance
At resonance, amplitude is maximum when driving frequency equals:
Select the correct option:
Solution
Natural frequency
Resonance occurs when a system is driven by an external periodic force whose frequency matches the system's own natural frequency of oscillation (fdrive≈fnatural).
- In this state, the system absorbs energy from the driver very efficiently, leading to a dramatic increase in the amplitude of oscillation.
- Examples include a child on a swing or the collapse of the Tacoma Narrows Bridge.
