For the conditions specified with Sample Problem 7/2, except that γ is increasing at the steady rate of 3π rad/sec, determine the angular velocity ω and the angular acceleration α of the rotor when the position γ = 30° is passed. (Suggestion: Apply Eq. 7/7 to the vector ω to find α. Note that Ω in Sample Problem 7/2 is no longer the complete angular velocity of the axes.)
