$6-61$ Figure P$6-24$ shows an inverted crank$-$slider mechanism. Link $2$ is $2\mathrm{.}5$ in long. The

distance $O_{4}A$ is $4\mathrm{.}1$ in and $O_2{O}_4$ is $3\mathrm{.}9$ in $.$ Find ${}_2,{}_3,{}_4,V_{A4},V_{\text{t}\text{r}\text{a}\text{n}\text{s}},$ and $V_{\text{s}\text{l}\text{i}\text{p}}$ for

the position shown with $V_{A2}=20i\frac{n}{sec}$ in the direction shown.
