The control moment gyro (CMG) shown in the two views below consists of a flywheel (centered at G) that rotates w.r.t. the base (A to

G

) that rotates w.r.t the ground at point A. If the angular velocity of the flywheel (w.r.t. the base) is

+8ra(d)/(s)

in the z direction shown and the angular velocity of the base (w.r.t. the ground) is a constant

+7ra(d)/(s)

in the

y

direction shown find the kinetic energy of the flywheel at the instant shown. Assumed the flywheel is a thin circular disk with a radius of 0.9 m and a mass of 4 kg . Answer in J . Side ered 131.22 רswer 71.69 margin of error + -
