Challenge Problems
Push your limits with challenges.
Question 1
Given an MDOF structure with three modes, derive the basic form of the equations of motion when no damping is present. Assume mass and stiffness are known.
💡 Hint: Use the natural frequency definitions and moment balance.
Question 2
Analyze how the modal responses would change if one of the mode shapes has a significantly higher natural frequency. What impact does this have on the total dynamic response?
💡 Hint: Consider the principle of resonance and mass participation.
