Question 2.
Name one method for combining modal responses.
Show hintHide hint
Think about statistical independence.
3Question 3.
What does modal analysis help engineers to do?
- Compute static loads
- Analyze dynamic responses
- Design aesthetics
Show hintHide hint
Think about how it influences the understanding of structures under dynamic loads.
4Question 4.
