The rotor of a turbojet engine of an aircraft has a mass 180 kg and polar moment of inertia 10 kg·m2 about the rotor axis. The rotor rotates at a constant speed of 1100 rad/s in the clockwise direction when viewed from the front of the aircraft. The aircraft while flying at a speed of 800 km per hour takes a turn with a radius of 1.5 km to the left. The gyroscopic moment exerted by the rotor on the aircraft structure and the direction of motion of the noseWhen the aircraft turns, are

• A. 1629.6 N·m and the nose goes up
• B. 1629.6 N·m and the nose goes down
• C. 162.9 N·m and the nose goes up
• D. 162.9 N·m and the nose goes down
