What is the effect of damping on resonance?.
- A.It increases the peak amplitude at resonance
- B.It decreases the peak amplitude at resonance
- C.It has no effect on the resonance frequency
- D.It shifts the natural frequency higher
Model answer
What a good answer should say
- It decreases the peak amplitude at resonance
Explanation
Why this works
Damping reduces the amplitude of oscillations at resonance, leading to a lower peak amplitude on the resonance curve.
