Question

The two rotors A and B are attached to the end of a shaft 500 mm long. The mass of the rotor A is
300 kg and its radius of gyration is 300 mm. The corresponding values of the rotor B are 500 kg
and 450 mm respectively. The shaft is 70 mm in diameter for the first 250 mm; 120 mm for the
next 70 mm and 100 mm diameter for the remaining length. The modulus of rigidity for the shaft
material is 80 GN/m2
. Find the position of the node at the actual shaft and the frequency of
torsional vibration.
