Question 1.
Define natural frequency.
Show hintHide hint
Think about how structures behave when not disturbed.
Question 2.
What is resonance?
Show hintHide hint
Consider how sounds may amplify in a room.
3Question 3.
What is the term for the frequency at which a structure tends to vibrate naturally?
- Damping
- Natural Frequency
- Resonance
Show hintHide hint
This is a foundational concept in structural dynamics.
4Question 4.
True or False: Damping significantly alters the natural frequency of a structure.
- True
- False
Show hintHide hint
Focus on the role of damping versus its effect.
Question 5.
A 10-story building has a natural frequency of 1 Hz. During an earthquake, the ground motion has a frequency of 1 Hz. Analyze the effect of this resonance without sufficient damping.
Show hintHide hint
Think about how resonance changes the amplitude of vibrations.
Question 6.
Propose an engineering solution to reduce the impact of resonance in a high-rise structure undergoing severe seismic loading.
Show hintHide hint
Consider how mass can be used to counteract movement.
