4 cards from this section. Quick, good the night before a test.
What does the orthogonality property of normal modes imply?
Think about how two different modes would behave geometrically!
Why is normalization important in modal analysis?
Consider why having a uniform scale would be beneficial.
What does orthogonality in normal modes imply?
Reflect on how distinct shapes behave separately.
True or False: Normalization is irrelevant in modal analysis.
Think about simplifying equations in mathematics.
Given a multi-degree-of-freedom system with specified mode shapes and participation factors, derive the total response under a known dynamic load. Consider different damping ratios in your evaluation.
Remember to consider how damping ratios can alter mode contributions effectively.
Analyze a case where the completeness fails due to a non-linear response in a real structure. Provide an extensive explanation of the implications and potential solutions.
Think about dynamic loads that could change behavior unexpectedly.
