Question 1
What does modal analysis allow us to do with MDOF systems?
- Make them more complex
- Simplify them to SDOF systems
- Eliminate dynamic behavior
💡 Hint: Think about what simplification means in structural context.
Question 2
True or False: Each mode contributes independently to the overall response.
- True
- False
💡 Hint: Consider how we analyze multiple responses together.

Challenge Problems
Push your limits with challenges.
Question 1
Given a 3-DOF system with known masses and stiffnesses, define the modal matrix, and compute the total response under a given loading condition.
💡 Hint: Use eigenvalue methods to derive the mode shapes first!
Question 2
Discuss the implications of using modal analysis for a highly damped structure; how does it affect the modal responses?
💡 Hint: Reflect on how damping might affect mode participation!
