The rotor of a turbine 13.6 kg in mass is supported at the midspan of a shaft with bearings 0.4064 m apart, as shown in Figure. The rotor is known to have an unbalance of 0.2879 kg . cm.
Determine the forces exerted on the bearings at a speed of 6000 rpm if the diameter of the steel shaft is 2.54 cm.
Compare this result with that of the same rotor mounted on a steel shaft of diameter l.905 cm. (Assume the shaft to be simply supported at the bearings.)
