A washing machine has 60 kg mass, and 15 cm tub radius. Machine dries the unbalanced 3 kg laundry by rotating with 1000 rpm. a) What would be the dynamic force transmitted to the foundation if there is no vibration isolation for the machine? b) An isolation with damping ratio 0.1 is applied to the machine. In this case, if the transmitted force is decreased by 90 % what would be the natural frequency of the machine?c) In this case, what would be the vibration amplitude of the machine?

Free Damped Vibrations

Free vibration is a type of vibration in which the external force is removed after giving the initial displacement to a body/system. In other words, in this type of vibration, force is applied at the initial displacement of the system, and after the initial displacement, force is removed, and the system vibrates at the natural frequency.
