SOLVE GRAPHICALLY: The mechanism shown in Figure $3$ has ${}_2=10ra\frac{d}{s}$

CW $($constant$).$ Link $2$ has an angle of $200$ with the positive X $-$

axis. For the shown configuration, find:

a$.$ The velocities: $v_D,{}_4,$ and ${}_5$

b$.$ The accelerations: $a_p,{}_4,$ and ${}_5$

You MUST use the velocity and acceleration images when possible.

$L_2=5,L_3=5,L_5=15,BC=8$

$O_2{O}_4=2\mathrm{.}5,O_{4}B=6,O_{4}C=6$
