14.8.3. Free Vibration Method

Try these first

1. 1.

   What is free vibration?

   Hint

   Think of what happens when you pluck a guitar string.

2. 2.

   Why is natural frequency important?

   Hint

   Consider resonance.

3. 3.

   What is the primary goal of the Free Vibration Method?

   • To increase mass
   • To determine natural frequency
   • To apply external forces

   Hint

   Consider the main use of free vibrations.

4. 4.

   True or False: The Free Vibration Method can provide insights into a structure's response without external driving forces.

   • True
   • False

   Hint

   Think about what 'free vibration' means.

5. 5.

   A building is displaced and allowed to vibrate. Describe the steps to analyze its natural frequency using the Free Vibration Method.

   Hint

   Think through all necessary measurements.

6. 6.

   Evaluate the potential consequences if engineers fail to apply the Free Vibration Method before constructing a large structure in a seismic zone.

   Hint

   Consider historical structures that faced resonance issues.
