QB1 (a) A motor gives gear A a clockwise angular velocity of @A rad/s and an anti- clockwise angular acceleration a rad/s, as shown in figure QB1. If the angular velocity of gear B is @B = 3 rad/s anticlockwise and its angular acceleration is B = 1 rad/s clockwise, find the values of (A and CA (the radius of gear A and gear B are, respectively, A=0.05m and B=0.15m) [8 marks] B 0.05 m 0.15 m Fig. QB1 (adapted from Hibbeler) (b) Calculate the velocity and acceleration of a point M on gear B situated a distance 0.1m from its center. [10 marks] (c) How long will it take for gear B to stop and how many revolutions will it have turned? [7 marks]
