Question 1.
What do eigenvalues represent in vibration analysis?
Show hintHide hint
Think about what frequencies matter in design.
Question 2.
What is the role of eigenvectors?
Show hintHide hint
Consider how a structure deforms during vibrations.
3Question 3.
What does vibration analysis help to prevent?
- Structural Damage
- Resonance
- Both
Show hintHide hint
Consider the consequences of unchecked vibrations.
4Question 4.
True or False: Eigenvalues indicate how a structure deforms under load.
- True
- False
Show hintHide hint
Think about what each term specifically relates to.
Question 5.
A structure is undergoing analysis for dynamic loading. The mass and stiffness matrices have been determined. Derive the characteristic polynomial to find the eigenvalues.
Show hintHide hint
Focus on the relationship between mass and stiffness.
Question 6.
How might the eigenvalues of a poorly designed bridge affect its performance and safety during an earthquake?
Show hintHide hint
Think about real-life cases of structural failures due to resonance.
