Question:

For the system shown in Fig. 3.49, $x$ and $y$ denote, respectively, the absolute displacements of the mass $m$ and the end $Q$ of the dashpot $c_{1}$.

(a) Derive the equation of motion of the mass $m$,

(b) find the steady-state displacement of the mass $m$, and

(c) find the force transmitted to the support at $P$, when the end $Q$ is subjected to the harmonic motion $y(t)=Y \cos \omega t$.
