Engineering Mechanics - Dynamics Chapter 18 The pendulum of the Charpy impact machine has mass M and radius of gyration k A . If it is released from rest when θ = 0 °, determine its angular velocity just before it strikes the specimen S , = 90 ° . Given: M 50 kg = k A 1.75 m = d 1.25 m = g 9.81 m s 2 = Solution: 0 Mgd + 1 2 Mk A 2 ω 2 2 = 2 2 gd k A 2 = 2 2.83 rad s = Problem 18-14 The pulley of mass M p has a radius of gyration about O of k O . If a motor M supplies a force to the cable of P = a ( b ce
