Unformatted text preview: At some instant in time, the angular velocity (rotational rate) is (rad/s). 2 . 7 . 6 . 3 2 1 b b b + = K For that instant, calculate the a) angular momentum vector b) angle between G K and H c) rotational kinetic energy T . 4. A satellite with principal MOIs I 1 = I 2 = 5000 kg m 2 and I 3 = 8000 kg m 2 is being forced to rotate with constant angular velocity (rotational rate) (rad/s) 8 . 4 . 3 . 3 2 1 b b b + + = G , where the b i are unit vectors along the principal axes. a. Calculate the torque required to maintain this motion. b. A torque is acting on the satellite, so why isnt the rotational rate increasing in magnitude?...
