The undamped naturalfrequency CO, and the damping ratio [ can be determined from a plot of the jiee motion of the system. If the damping is light, ( < 0.2, the lqqarithmic decrement can be used to determine the coeficients. Systems with moderate damping are those in the range 0.2 < ( -C 1.2. A metho
