Two rotors A and B are connected to the two ends of a shaft of uniform diameter. The mass moment of inertia of rotor A about the axis of the shaft is four times that of H. If the length of the shaft is I m and c is the position of node for tensional vibrations then what is the length if AC?
(a) 1/5 m (b) 4/5 m (c) 1/25 m (d) 16/25 m
