An advertisement board was pulled from the top point with a horizontal force of 100 kN with the help of a jack and subjected to 75 mm horizontal displacement. When the force is released suddenly, the time elapsed at the end of the 5th oscillation was measured as 1.50 seconds and the amplitude as 30 mm. 75 mm a ) Find the damping ratio of the system. b ) Find the natural vibration period Tn of the system and the damped period Td of the system. c) Find the horizontal translational stiffness of the system.
