4 Two rotors I, and I are mounted on a shaft with a free length of 54 cm and 4.5 cm shafting between them. At a distance of 33 cm from I,, it is desired to take-off a drive which shall be free from oscillatory movement and to effect this, the remaining 21 cm of shaft adjacent to his reduced in diameter. For 1, mass = 48 kg, radius of gyration = 14 cm, and for I, mass = 18 kg, radius of gyration = 17 cm. Find the frequency of natural vibration of the system and the diameter of the reduced portion of shaft.
