Using the vector loop method, Given a fourbar linkage with the link lengths RO$2$O$4$

$=250mm,RO2A=50mm,$RAB$=150mm,RO4B=160mm.$ For $2=40$ and $2=-4de\frac{g}{sec}$ find

the values $3$ and $4.$ Then, find the $3$ and $4,$ VA$,$ VBA, and VB analytically $($symbolic$).$ Also,

when $2$ changes from $80$ to $40$ please plot:

$3$ vs $2($deg vs$.$ deg$)$

$4$ vs $2($deg vs$.$ deg$)$

w$2$ vs $2($deg$/$s vs$.$ deg$)$

$3$ vs $2($deg$/$s vs$.$ deg$)$

$w4vs2($deg$/$s vs$.$ deg$).$
