Question

A motion is aperiodic when the value of the damping factor is _______.

Answer 1

I don't know what is answer

Answer 2

A motion is aperiodic when the value of the damping factor is is 1.0 or above.

Explanation:

• It could have both a periodic motion or an aperiodic motion depending at the system damping.

• Damping ratio is the ratio of the actual damping coefficient that is represented by  (c) to the critical damping coefficient represented as (cc) and is referred to as damping factor or damping ratio.

• It results in aperiodic motion when the damping factor is greater than equal to 1.
• This resultant motion is oscillatory with decreasing amplitudes having a frequency of ωd.
