Challenge Problems
Push your limits with challenges.
Question 1
Given a two-mass system with natural frequencies ω1 = 3 rad/s and ω2 = 5 rad/s, and respective damping ratios ξ1 = 0.05 and ξ2 = 0.03, write the modal equations for each mass and solve for q(t).
💡 Hint: Break each function into its individual parts and consider the effects of damping.
Question 2
Analyze a system where four modes affect total displacement. If modes 1 and 2 comprise 85% of the response, should you ignore modes 3 and 4? Discuss.
💡 Hint: Think about how even small contributions can affect overall system safety.
