1. The flywheel of the gyroscope rotates about its own axis at 02= 6,000 rev/min. At the instant when

= 120°, the inner gimbal support is rotating relative to the outer gimbal at 6 rad/s and 0 = -90

rad/s². The corresponding rotation of the outer gimbal about the horizontal axis is co₁ = 10 rad/s and

100 rad/s². Determine the angular velocity and angular acceleration of the flywheel at this

instant.
