A damped system is driven by a harmonic force ft18 sin12t

A damped system is driven by a harmonic force F(t)=18 sin(12t). The system has a mass of 17.5 kg and damping constant of 42 N/s/m.

a) Determine the spring constant k which produces maximum amplitude response. Also find out the maximum amplitude; (b) If k = 4 kN/m, how much is the steady state amplitude?
