§ Since the peak is achieved at w max = 0.8483, exciting the system using the following sinusoidal input
•                        
•
• gives the steady-state response of the system as
•
•
§ This shows that the system response will be amplified 11.47 times for an input signal at the frequency wmax, which could be undesirable if F1 and F2 are disturbance force and x1 and x2 are the positions to be kept steady.
