Mechanical impedance is the ratio of - Automatic Control Systems

Electronics and Communication Engineering (ECE) : Automatic Control Systems - Quiz(MCQ)

Mechanical impedance is the ratio of

rms force to rms velocity

rms force to rms displacement

rms velocity to rms displacement

None of the above

Correct Answer : Option (A) : rms force to rms velocity

Explanation : In force voltage analogy force is analogous to voltage and velocity to current. Just as v/i = z , force/velocity = mechanical impedance.
