Problem is here,

I'm looking at this problem with the top and bottom beams being separate members and doing a FBD of both separately. However I'm unsure about the points where we have tension/compression. Like at point B, do I include a y component and the tension, or just tension? My first instinct was to not include the y component by itself, but the problem asks to find the reactions at point B, so wouldn't that need to be broken down into x and y?
Doing the latter, what I was thinking is taking a moment about D and going from there.
MD = (0.8)TBEsin51.3 + (1.2)TFCsin68.2
I would then solve for one of those variables, take the moment about A in the other diagram, and and plug in. Would that be correct?
Also, for distributed force, would it be 400(1.4), with the distance being it is acting on the top member be [400(1.4)][0.7]?
Thanks
