Question:

An exhaust fan of mass 400 kg is mounted on an elastic support having a spring constant of 80 kN/m and a damping ratio of 2%. If the fan has a rotating unbalance of 0.15 kg•m and operates at 1,800 rpm, determine

(a) The steady-state amplitude of vibration of the fan;

(b) The force transmitted to the ground;

(c) The new spring constant of the elastic support such that there is no more than 50% of the unbalanced force transmitted to the ground.
