15 mm diameter shaft rotates in long fixed bearings 60 cm apart. A rotor of mass 20 kg is mounted at mid span. The mass center of rotor is 0.5 mm from the shaft axis. If the bending stress in the shaft is not to exceed 120 MPa. Find range of speed over which the shaft must not run. Take modulus of elasticity for the shaft material as 200kN/m²
