( mo то 1) A device to produce vibrations for laboratory tests consists of the two counter-rotating wheels, each carrying an eccentric mass mo = 1 kg with a center of mass at a distance e = 0.1 m from its axis of rotation. The wheels are synchronized so that the vertical positions of the unbalanced masses are always identical. The total mass of the device including the unbalance is m = 10 kg. The stiffness and the damping values of the mounting are k = 1000 N/m and c = 50 Ns/m. Determine the amplitude of the steady- state vibrations when the wheels are rotating at w = 200 rad/s.
