Fоr the оne-degree-оf-freedom system below, there аre externаl forces аcting on each mass element and an external torque applied to the rotating element. Assume small motions and that the cables between the rotating element and the masses are rigid and inextensible. Using energy methods: Derive the equivalent mass, with respect to (10 pts) Derive the equivalent stiffness, , with respect to (10 pts) Derive the equivalent damping, , with respect to (10 pts) Derive the equivalent force, , with respect to (10 pts) Write a single equation of motion with respect to (5 points)
