Question 1
What does the principle of modal superposition state?
- The response of an MDOF system can be reduced to a single vibration mode.
- The response of an MDOF system is a sum of independent SDOF responses.
- The response does not depend on the mode shapes.
💡 Hint: Think about how we divide complex systems into simpler parts.
Question 2
True or False: Mode shapes can affect each other in modal superposition.
- True
- False
💡 Hint: Recall the definition of orthogonality.
