Finding Resultant Force on Beam: F1 & F2

[Ry122]

http://users.on.net/~rohanlal/Q16.jpg
Is the magnitude of the single resultant force found by finding the y components of the forces that are acting on the beam then subtracting them from each other? Is the horizontal component of F1 ignored?

Also, the line of action of F1 is supposed to be 1.384M. How is this value determined?

The force, F1, acts on the beam at a distance/displacement 0.2 m from the axis passing through O. Draw a line parallel and through F1, and determine how far from O that line through F1 intersects the axis.

Could you also tell me if my method of finding the resultant force is correct? thanks
