The below graph shows the rotation rate dependence of the steady-state amplitude of a single degree of freedom (SDOF) system supporting a motor. The generalized mass of the system is M=500-kg. From the below provided data, deduce the natural frequency, the bandwidth of the resonance, the critical damping ratio, the imbalance em, and the smallest possible amplitude when the motor rotates above 80-rev/s.
