Question

EXERCISE 3.28 The entire system rotates about the vertical axis at constant angular speed , and the rotation rate 2 of the ro- tor relative to bar BC also is constant. (a) Describe the angular velocity of the rotor in terms of a superposition of simple rota- tions. (b) Solely from an examination of the description in Part (a), predict the direction(s) in which the angular acceleration of the rotor will be situated relative to the xyz axes defined in the sketch. Briefly explain your answer. (c) Describe the angular ve- locity and angular acceleration of the rotor in terms of compo- nents relative to xyz. 0 40^ Exercise 3.28
