A two$-$bar linkage shown is supported by a pin and bracket at point $B$ and by a collar at point $D$ that slides freely on a vertical pin allows member ABC to rotate around point $B.$ The collar allows the member EDFC to move vertically at point $D,$ but not to around point $D.$ Determine the force $$ required to maintain the equilibrium of the linkage.

Dimension w $=10\mathrm{.}1$ inches

Force $R=670$ pounds

Force $Q=395$ pounds

What is the numerical relationship between ${}_{yC}$ and ${}_{yA}?($Type in a positive three decimal number$)$

What is force $P$ in pounds? $($Type in a positive integer.$)$

$$yC$/\frac{?}{\text{b}\text{a}\text{r}}(yA)=$

$P=$ pounds
