Q10 The 30 kg pendulum in Figure 10 has its mass center at G and a radius of gyration about point G of kG = 300 mm. If it is released from rest when 0 = 0, determine its angular velocity at the instant 0 = 90. Spring AB has a stiffness of k = 300 N/m and is unstretched when 0 = 0. 0.6 m B 0.35 m G k = 300 N/m 0.1 m Figure Q10
