Question $2$:

The offset slider$-$crank linkage is driven by crank $2.$

a$)$ Write the loop$-$closure equation and indicate on the vectors the known and

unknown information $($for example $R_{BA}^{\sqrt[\phantom{2}]{?}?}$ shows that the size of vector is known but

the direction is unknown.$)$

b$)$ Using a graphical approach, solve for $R_{BO}$ given the following:

$R_{AO}=2\mathrm{.}5in,R_{BA}=6in,R_{CB}=17\mathrm{.}5in,$ and $R_{CO}=22\mathrm{.}5in.$
