Can anyone give me some guidance with a statics 3-pinned arch problem? (see details)

I have figured out A_y and E_y by finding the resultant forces of the distributed loads, then taking the moment about A to get E_y, then summing the Y-forces to get A_y.
I got E_y=7560#, and A_y=3240#.

Now, I know I need to make a cut, but I do not know where/how to take it. Do I cut vertically at C? and if I do, does that expose a horizontal force in member BE? Or do I cut just to the right of B? What is the next step?

Sounds like homework for Engineering Statics.

Are you in an Engineering class?

Yes. I’ve looked in the text book, but there’s no similar problem with a horizontal beam instead of two pin connections. Also no examples with a distributive load instead of a point load. Any suggestions?

What did your instructor teach you about how to handle this sort of problem?

Nothing. We haven’t done any examples in class with this extra beam and pin connections. Only basic 3-pinned arches.
