  • Question
  • Mechanical impedance is the ratio of


  • Options
  • A. rms force to rms velocity
  • B. rms force to rms displacement
  • C. rms velocity to rms displacement
  • D. none of the above

  • Correct Answer
  • rms force to rms velocity 

    Explanation
    In force voltage analogy force is analogous to voltage and velocity to current. Just as Mechanical impedance is the ratio of rms force to rms velocity rms force to rms displacement rms vel, force/velocity = mechanical impedance.
