Show hintHide hint
It's a comparison metric!
Question 2.
What happens at a frequency ratio close to 1?
Show hintHide hint
Think about risks during earthquakes.
3Question 3.
What does the frequency ratio illustrate?
- A measure of stability
- A comparison of excitation to natural frequency

Show hintHide hint
Think about dynamic forces!
4Question 4.
Does resonance occur when the frequency ratio is approximately 1?
- True
- False
Show hintHide hint
It's all about alignment!
Question 5.
A building has a natural frequency of 3 Hz, what should the forcing frequency be to avoid resonance?
Show hintHide hint
Think about frequency ranges.
Question 6.
Given that a high-rise building's natural frequency is observed to change due to modifications made, discuss the implications of this change if not addressed.
