Question 1
Given a 2-DOF system defined by masses m1 = 1500kg, m2 = 2000kg, and stiffness k1 = 30000N/m, k2 = 25000N/m, k12 = 5000N/m. Derive the equations of motion.
💡 Hint: Recall how to express dynamics through mass and stiffness matrices.
Question 2
A 2-DOF system has two natural frequencies of 5Hz and 7Hz. What will be the effect on resonance if the system is excited near these frequencies?
💡 Hint: Think about how objects resonate and the importance of matching frequencies.
