Question:

The vertical motion of a machine is measured by using the arrangement shown in Fig. 10.43. The motion of the mass $m$ relative to the machine body is recorded on a drum. If the damping constant $c$ is equal to $c_{\text {cri }} / \sqrt{2}$, and the vertical vibration of the machine body is given by $y(t)=Y \sin \omega t$, find the amplitude of motion recorded on the drum.
