Challenge Problems
Push your limits with challenges.
Question 1
A structure experiences vibrations with known mode shapes. If you are tasked with computing responses to dynamic loading, how would orthogonality assist you?
💡 Hint: Focus on the separability of the equations.
Question 2
Consider a scenario where a set of mode shapes were not orthogonal. What consequences could arise in terms of computational efficiency?
💡 Hint: Think about how overlapping vectors affect problem-solving.
