8.13.1. Definition and Implications

Try these first

1. 1.

   Define resonance in your own words.

   Hint

   Focus on the relationship between forcing and natural frequencies.

2. 2.

   What is meant by natural frequency?

   Hint

   Consider how objects vibrate when disturbed.

3. 3.

   What is resonance?

   • A type of sound
   • When forcing frequency matches natural frequency
   • A type of damping

   Hint

   Remember the relationship between two frequencies.

4. 4.

   Does damping help in reducing the effects of resonance?

   • True
   • False

   Hint

   Think about vibration control mechanisms.

5. 5.

   Design a simple structure (like a bridge) ensuring its natural frequency does not match expected traffic resonance frequencies. Explain your reasoning.

   Hint

   Consider the relationship between speed, frequency, and design.

6. 6.

   Evaluate the implications of not using damping in a high-rise building situated in an earthquake-prone area. What would be the consequences?

   Hint

   Reflect on the importance of energy dissipation in seismic events.
