Three forces and a couple are applied to a bracket as shown. The origin of the xy$-$axes is at $0.$

$F1=90N,F2=180N,F3=60N,m=180N.m$ and $a=380mm$

a$.$ Determine the equivalent force$-$couple resultant acting at $0.$

Resultant force Component in $x$ direction $=$ in

Resultant force Component in y direction $=$ j $N$

Moment $Mo=N.m$

b$.$ Determine the distance XR where the equivalent single force line of action intercept the $x-$axis measured from $0.$

Distance $xR=mm$
