Question 1.
Define resonance in your own words.
Show hintHide hint
Focus on the relationship between forcing and natural frequencies.
Question 2.
What is meant by natural frequency?
Show hintHide hint
Consider how objects vibrate when disturbed.
3Question 3.
What is resonance?
- A type of sound
- When forcing frequency matches natural frequency
- A type of damping
Show hintHide hint
Remember the relationship between two frequencies.
4Question 4.
Does damping help in reducing the effects of resonance?
- True
- False
Show hintHide hint
Think about vibration control mechanisms.
Question 5.
Design a simple structure (like a bridge) ensuring its natural frequency does not match expected traffic resonance frequencies. Explain your reasoning.
Show hintHide hint
Consider the relationship between speed, frequency, and design.
Question 6.
Evaluate the implications of not using damping in a high-rise building situated in an earthquake-prone area. What would be the consequences?
Show hintHide hint
