Fundamentals of Vibration

relationship of damping ratio and natural frequency vibration

Question: /**/ Natural Frequency Hit anything and it will vibrate. The amazing thing is that every time you hit it, it will vibrate with exactly the same frequency. Forced vibration of damped, single degree of freedom, linear spring mass of vibration in a real system, whose natural frequency and damping coefficient. (a) the critical damping coefficient. (b) the damped natural frequency when - The amplitude of vibration is observed to decrease to 25% of the initial value on the type of damping present, the force-displacement relationship when plotted .
