Engineering Mechanics - Dynamics Chapter 16 r A 0.05 m = r B 0.15 m = θ 1 10 rev = Solution: α A a 3 b + = ω A 2 A0 2 2 0 1 a 3 b + () d + = A A0 2 2 0 1 a 3 b + d + = A 1395.94 rad s = B r A r B A = B 465 rad s = Problem 16-23 A motor gives gear A angular acceleration A = kt 3 . If this gear is initially turning with angular velocity A0 , determine the angular velocity of gear B when t = t 1 . Given: t 1 2s = k 4 rad s 5 = r A 0.05 m = A0 20 rad s = r B 0.15 m = Solution: tt 1 = A kt 3 = A k 4 t 4 A0 + = A 36.00 rad s = B r A r B A = B 12.00 rad s = *Problem 16-24 For a short time a motor of the random-orbit sander drives the gear A with an angular velocity
