A horizontal shaft of diameter 48 mm consists of a gear of mass 24 kg. The horizontal shaft is simply supported at both ends on bearings. The distance between the bearings is 2 m. The shaft rotates at 4800 RPM. The shaft has some manufacturing defect and the center of mass of the rotor deviates from the geometric center of the rotor by 0.22 mm. Determine the amplitude of the steady-state vibration. E = 200 GN/m².
