Challenge Problems
Push your limits with challenges.
Question 1
A bridge is designed with a damping coefficient c of 50 N·s/m and a mass m of 1000 kg. Calculate the damping ratio (ζ) if the stiffness k is 2000 N/m.
💡 Hint: Use the relationship between mass, stiffness, and critical damping.
Question 2
How would the response of an SDOF system change if the damping ratio increases from 0.5 to 1.0? Discuss the implications for structural design.
💡 Hint: Consider how quickly the structure returns to equilibrium.
