If the angular velocity w 0 = 4j 3k rad/s of the rotor in Prob. 7/5

Question:

If the angular velocity w0 = −4j − 3k rad/s of the rotor in Prob. 7/5 is constant in magnitude, determine the angular acceleration a of the rotor for (a) Ω = 0 and θ˙ = 2 rad/s (both constant) and (b) θ = tan−1(3/4) and Ω = 2 rad/s (both constant). Find the magnitude of the acceleration of point A in each case, where A has the position vector r = 0.5i +1.2j +1.1k m at the instant represented.
