5 cards from this section. Quick, good the night before a test.
What is damping?
Think about how a swing slows down.
Define orthogonality in the context of vibration modes.
Consider how different instruments play in an orchestra.
What happens to mode shapes in damped systems?
Recall how damping introduces interaction between modes.
True or False: Classical damping leads to coupled modal equations.
Consider the relationship between damping and mode independence.
A building has a fundamental frequency of 1 Hz and a damping ratio of 0.3. What type of damping does it exhibit, and how would it generally behave under dynamic loads?
Remember the definitions of damping types.
Analyze a system with non-classical damping. If mode shapes are coupled, what implications does this have for the design of structures in seismic zones?
Consider how design requires knowledge of mode interactions for proper seismic performance.
