Challenge Problems

Push your limits with challenges.

Question 1

Given a simple two-degree of freedom mass-spring system, derive the eigenvalue equation and find the natural frequencies if the stiffness matrix is K and mass matrix is M.

💡 Hint: Consider the dimensional consistency of the derived matrices during transformation.

Question 2

Analyze a case where a structure experiences resonance due to a specific external forcing frequency. What mitigation strategies could be employed using eigenvalue analysis?

💡 Hint: Think about how to avoid matching frequencies.
