Question 1.
What happens when external forces match a structure's natural frequency?
Show hintHide hint
Think about the effects of matching frequencies in sound.
Question 2.
What is one method to avoid resonance in structural design?
Show hintHide hint
Recall the concept of frequency adjustment.
3Question 3.
What is resonance?
- A structural failure
- Amplified vibrations due to frequency match

- True
- False
Show hintHide hint
Consider the role of isolators in seismic design.
Question 5.
Given a scenario where a high-rise building is designed in a seismically active city, outline a strategy to ensure it avoids resonance.
Show hintHide hint
Consider factors mentioned in the lessons about damping and mass changes.
Question 6.
Evaluate the impact of ignoring resonance in structural design, citing real-world examples to support your answer.
Show hintHide hint
Look into historical earthquake case studies for supporting details.
