Solve the all parts of following question:
Question: An unbalanced electric motor is mounted on a vibration isolator. If the stedy-state amplitude of vibration of the motor is 20 mm at resonance and 5 mm away from resonance (w/wn =0), determine:
Part A: Determine the isolator damping ratio?
Part B: Determine the unbalanced force produced by the motor if the isolator stiffness is 1000 N/m?
Please show all work and steps I am really trying to learn this for my test.
