Exam-style question
Try this first
Explain how damping affects the amplitude of a vibrating system and describe its impact on the resonance curve.
Model answer
What a good answer should say
- Damping reduces the amplitude of oscillations in a vibrating system.
- As damping increases, the peak amplitude at resonance decreases, leading to a broader resonance curve.
- This means that the system can respond to a wider range of driving frequencies, but with less maximum amplitude.
Explanation
Why this works
This answer effectively describes the relationship between damping and amplitude, as well as how it alters the resonance curve, testing the understanding of forced vibrations and resonance concepts.
