When a base vibrates and causes a machine that is placed on

When a base vibrates and causes a machine that is placed on the base to vibrate. The ratio of the steady state vibration amplitude of the machine relative to the base is known as Displacement transmissible Logarithmic decrement Damping factor Multiple ratio

Solution

Ans: Displacement transmissibility

It represents the ratio of the amplitude of the force (or vibration) transmitted to the supporting structure, to that of exciting force.

Logarithmic decrement: Natural log of ratio of the amplitudes of two successive peaks.

Damping factor: ratio of nominal loudspeaker impedance to the total impedance that is driving it
