Engineering Mechanics - Dynamics Chapter 21 M x 0 = M y k y sin θ () = k y 0.036 Nm = M z k z sin 2 () = k z 0.0030 N m = Problem 21-55 The cylinder has mass m c and is mounted on an axle that is supported by bearings at A and B . If the axle is turning at ω j , determine the vertical components of force acting at the bearings at this instant. Units Used: kN 10 3 N = Given: m c 30 kg = a 1m = ω 40 rad s = d 0.5 m = L 1.5 m = g 9.81 m s 2 = Solution: atan d L = I x' m c L 2 12
