Challenge Problems
Push your limits with challenges.
Question 1
Given a structure with a mass of 500 kg, a damping coefficient of 200 Ns/m, and a stiffness of 30000 N/m, calculate the damping ratio. Discuss its significance in designing for forced vibrations.
💡 Hint: Use the formula ζ = c/(2*sqrt(m*k)) and plug in the values.
Question 2
Analyze how increasing the damping coefficient influences the transient and steady-state responses of a structure under forced vibration.
💡 Hint: Consider how energy dissipation connects to structural performance.
