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.

Angular movements are produced when the angle between the bones of joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. The extension is the opposite of flexion in that the angle between the bones of a joint increase.
