Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does the undamped natural frequency represent?
- Vibrations with external damping
- The natural frequency when a system oscillates freely
- A measure of mass only
💡 Hint: Think about conditions without external forces.
Question 2
True or False: Increasing mass decreases the undamped natural frequency.
- True
- False
💡 Hint: Consider how mass impacts the frequency derived from the formula.

Challenge Problems
Push your limits with challenges.
Question 1
A building has a natural frequency of 2 rad/s. If the stiffness is changed to 800 N/m while maintaining the mass, what new natural frequency will be calculated?
💡 Hint: Use the formula to relate stiffness, mass, and frequency.
Question 2
Discuss how varying environmental factors (like soil conditions) might affect a structure's undamped natural frequency.
💡 Hint: Consider the impact of flexibility or rigidity from the surrounding environment.
