Challenge Problems
Push your limits with advanced challenges
A structure designed to withstand seismic forces has a natural frequency of 1 Hz. If the system incorporates a damper with a damping coefficient of 10 Ns/m, what is the damping ratio if its mass is 50 kg and stiffness is 250 N/m?
💡 Hint: Ensure all variables are identified clearly prior to calculation.
Evaluate how introducing a damping coefficient affects the oscillation period of a system with mass 15 kg and stiffness 300 N/m.
💡 Hint: Remember that putting in damping changes oscillation behavior slightly but primarily affects decay of amplitude.
