When the damping co-efficient (ξ) is unity, the system is __________________?
Correct answer: B. Critically damped
- A. Overdamped
- B. Critically damped
- C. Underdamped
- D. Highly fluctuating
Explanation
A damping ratio of unity means the two characteristic roots coincide on the negative real axis, giving the fastest response without oscillation. This condition is called critical damping.
