1. A nominal level of damping is assumed ( 5 % of critical damping ). 2. For the case of critical damping , 3. If the damping is increased past critical damping , the system is " overdamped ". 4. The value that the damping coefficient must reach for critical damping in the mass spring damper model is: 5. The damping ratio provides a mathematical means of expressing the level of damping in a system relative to critical damping . 6. This damping ratio is just a ratio of the actual damping over the amount of damping required to reach critical damping . 7. Ideally, the natural frequency should be high and the damping factor should be near 0.707 ( critical damping ). 8. The value of damping that causes the oscillatory motion to settle quickest is called the critical damping C _ c \,: 9. The special case of 1 } } is called critical damping and represents the case of a circuit that is just on the border of oscillation. 10. If damping is increased just to the point where the system no longer oscillates, the system has reached the point of " critical damping ".
