Figure Q3 shows a vibrating system consists of a slender bar and a pulley. Spring stiffness, K and damping coefficient, C shown are 10 kN/m and 5 kNs/m respectively. Mass moment of inertia of the slender bar about fixed point B is 1 kgm. Determine the following. i. ii. Determine natural frequency of the system shown by taking equivalent mass, stiffness and damping at point A. Determine damped vibration period of the system shown.
