Xosin(ot) Shown in the figure below is a rigid pendulum bar of I= 1 m and mass m, 1 kg attached to a roller, of mass m, = 0.2 kg, whose motion is described by X, sin(@t), Xo = 1 [m]. Model the pendulum bar as a uniform slender rod which has a moment of inertia with respect to its mass centre Ig given by m1/12. Use tangential-normal coordinate system to analyze the dynamics of the pendulum bar and use...
