7. The rotor of a turbine installed in a boat with its axis along the longitudinal axis of the boat makes 1500 rp.m. clockwise when viewed from the stern. The rotor has a mass of 750 kg and a radius of gyration of 300 mm. If at an instant, the boat pitches in the longitudinal vertical plane so that the bow rises from the horizontal plane with an angular velocity of I rad/s, determine the torque acting on the boat and the dircction in which it tends to turn the boat at the instant. [Ans. 10.6 kN-m]

7.
The rotor of a turbine installed in a boat with its axis along the longitudinal axis of the boat makes
1500 rp.m. clockwise when viewed from the stern. The rotor has a mass of 750 kg and a radius of
gyration of 300 mm. If at an instant, the boat pitches in the longitudinal vertical plane so that the bow
rises from the horizontal plane with an angular velocity of I rad/s, determine the torque acting on the
[Ans. 10.6 kN-m]
boat and the direction in which it tends to turn the boat at the instant.
