Exam-style question
Try this first
If a system has a natural frequency of 5 Hz, what happens when it is driven at 5 Hz?.
- A.The system will oscillate with maximum amplitude
- B.The system will not oscillate
- C.The system will oscillate with minimum amplitude
- D.The system will oscillate at a different frequency
Model answer
What a good answer should say
- The system will oscillate with maximum amplitude
Explanation
Why this works
When the driving frequency matches the natural frequency, resonance occurs, resulting in maximum amplitude of oscillation.
