A 0.2-kg spool slides down along a smooth rod.If the rod has a constant angular rate of rotation= 2 rad/s in the vertical plane, show that the equationsof motion for the spool are i – 4r – 9.81 sin 0 = 0and 0.8i + N, - 1.962 cos 0 = 0, where N, is the magnitudeof the normal force of the rod on the spool. Using themethods of differential equations, it can be shown thatthe solution of the first of these equations isr = Cje " + Cze – (9.81/8) sin 2t. If r, i, and 0 are zerowhen i = 0, evaluate the constants C, and C, determine rat the instant 0 = 7/4 rad.%3D-21e = 2 rad/s
