2.3.3. Resonance and Damping Effect

Try these first

1. 1.

   What is resonance in a structural system?

   Hint

   Think about how musical instruments resonate.

2. 2.

   How does damping affect vibrations?

   Hint

   Consider how shock absorbers work in vehicles.

3. 3.

   What occurs during resonance?

   • Lower amplitude
   • Increased vibration amplitude
   • No effect at all

   Hint

   Remember high vibrations at matching frequencies!

4. 4.

   True or False: Damping completely prevents resonance.

   • True
   • False

   Hint

   Consider the fact that resonance can still occur even with damping present.

5. 5.

   If a building has a natural frequency of 2 Hz and is subjected to an earthquake at a frequency of 2 Hz, what are the potential consequences if no damping is present?

   Hint

   Consider the impact of matching frequencies.

6. 6.

   Design a scenario where adding damping significantly changed the response of a system experiencing resonance. Describe the before and after effects.

   Hint

   Think about different engineering applications and the prior consequences of non-damped systems.
