A couple is two forces acting in parallel and opposite directions.

F1=20N

F2=22N

F3-18N

Couple=15N

I have to determine the magnitude and direction of a single force that has the same effect on the beam as F1+F2+F3+ the couple. To do this would I find the sum of all the x and y components of these forces, then find the resultant of the x and y and make it negative?

Also, im having trouble understanding the diagram. Which ways is the couple exerting force on the beam?
