(a) For a pendulum system (Fig. 1.1), derive its dynamic equation using the Lagrange- method (Fig. 1.2). Assume that there is a torsional spring with a stiffness of K at the pivot, that the mass is only at the end, and that there is viscous friction with a factor of F at the pivot. The applied external torque is T.
