4 cards from this section. Quick, good the night before a test.
What does orthogonality in mode shapes mean?
Consider if they interact or not.
Give an example of an MDOF system.
Think of structures sensitive to vibrations.
What is orthogonality in the context of mode shapes?
Think about how they relate to each other.
True or False: The dot product of orthogonal mode shapes equals zero.
Focus on the mathematical definition.
Given a multi-degree-of-freedom structural system with three distinct modes, derive the response expression if the modes are orthogonal.
Consider how each mode's contribution adds up without interference.
Discuss the implications of ignoring the orthogonality of modes in a structural analysis scenario.
Think about how calculations could become complex.
