Engineering Mechanics - Dynamics Chapter 16 Problem 16-62 At the instant shown, the truck is traveling to the right at speed v . If the spool does not slip at B , determine its angular velocity so that its mass center G appears to an observer on the ground to remain stationary. Given: v 8 m s = r 1.5 m = Solution: v G vv GB + = 0 v ω r = v r = 5.33 rad s = Problem 16-63 If, at a given instant, point B has a downward velocity of v B , determine the velocity of point A at this instant. Notice that for this motion to occur, the wheel must slip at
