A vibrating system is characterized by the following parameters.
Mass = m = 6 kg
Stiffness of spring = k = 200 N/m
Damping coefficient of the dashpot = c
= 6 N s/m
Determine
(i) The damping factor
(ii) The natural frequency of damped vibration
(iii) The number of cycles after which of the original amplitude is reduced to 20 percent.
