CW) An electric motor of weight W = 9100 N is installed at the middle of a simply supported beam and has the operating angular speed of 600 rpm. The centrifugal force due to the unbalanced rotor is F0 = 2270 N. The static displacement is δ = 0.00254 m, and the damping coefficient provides the amplitude drop at twice as many per 10 cycles of free vibrations. Ignoring the beam's inertia, determine the amplitude of steady-state vibrations during the operating regime. Ignore the lateral motion component.
