Engineering Mechanics - Dynamics Chapter 17 F B L 2 F A L 2 1 12 W g L 2 α = 6 F B F A ( ) g WL = 5.796 rad s 2 = Problem 17-93 The spool has mass M and radius of gyration k G . It rests on the surface of a conveyor belt for which the coefficient of static friction is μ s and the coefficient of kinetic friction is k . If the conveyor accelerates at rate a C , determine the initial tension in the wire and the angular acceleration of the spool. The spool is originally at rest. Units Used: kN 10 3 N = Given: M 500 kg = a C 1 m s 2 = k G 1.30 m = r i 0.8 m = s 0.5 = r o 1.6 m = k 0.4 = Solution: Assume no slip Guesses 1 rad s 2 = a x 1 m s 2 = T 1N = F max 1N = N s 1N = F s 1N =
