A vehicle suspension system has a mass of 1000 kg, damping coefficient of 2000 Ns/m, and spring constant of 25000 N/m. Calculate the damping ratio and natural frequency, then discuss the implications of these results for ride comfort.
💡 Hint: Remember to apply the appropriate formulas to find both values.
Design a damped system for a tall building with a mass of 4000 kg and a damping coefficient of 1000 Ns/m for a stiffness of 90000 N/m. How would you calculate damping ratio and natural frequency to ensure the structure can withstand strong winds?
💡 Hint: Focus on how you would balance comfort with structural integrity in your calculations.
