Challenge Problems

Push your limits with challenges.

Question 1

Given a real-world structure with multiple vibrational modes, N, list the key steps to determine which modes retain their orthogonality and arrange them accordingly.

💡 Hint: Consider the mathematical principles that support establishing independence.

Question 2

Analyze a coupled multi-degree-of-freedom system with three unknown mode shapes. Discuss how each mode's interaction can be translated into an equation of motion given their orthogonal properties.

💡 Hint: Think about how to express one mode's influence without impacting others.
