Challenge Problems
Push your limits with challenges.
Question 1
Consider an SDOF system where mass m is 10 kg, damping coefficient c is 5 Ns/m, and stiffness k is 100 N/m. Calculate the natural frequency of the system.
💡 Hint: Use the formula for natural frequency and plug in the given values.
Question 2
Discuss the differences in the equation of motion between an underdamped and overdamped system and calculate the respective damping ratios if m=1 kg, c=0.5 Ns/m for the underdamped case, and c=2 Ns/m for the overdamped case with k=4 N/m.
💡 Hint: Remember that ζ < 1 denotes underdamping and ζ > 1 denotes overdamping.
