What does the stiffness matrix (K) represent in structural dynamics?
💡 Hint: Think about how materials behave under load.
True or False: Eigenvectors can only represent one vibration mode in a system.
💡 Hint: Relate this to how many ways structures can vibrate.

Challenge Problems
Push your limits with advanced challenges
Consider a two-story building represented by a simplified paper model. Using the principles discussed, predict how the building might behave during an earthquake and determine which mode shapes could be critical in your analysis.
💡 Hint: Think about how height and weight distribution might affect vibration.
Analyze two scenarios: one where a structure has well-separated natural frequencies and another where frequencies are closely spaced. Discuss the implications on structural performance under dynamic loading.
💡 Hint: Consider why resonance can be a danger to structures.
