A machine part is modeled as a pendulum connected to a spring and damper as illustrated. The mass of the pendulum rod is $m_r = 2$ kg and the mass at the pendulum tip is $m = 8$ kg, the spring stiffness is k=250 N/m, and the damping coefficient is c = 7 N.s/m. The length of the rod is L = 1 m and length $l = 0.5$ m. Note: The weights of both the tip mass and the rod mass are included in the equation of motion.
