I'm trying to make sure I have a beam size calculated

Customer Question

I'm trying to make sure I have a beam size calculated correctly. It's a main roof beam that will support three symmetrically placed concentrated loads (1 at mid span and the other two point loads equally spaced on either side). All three point loads are at 3000 lbs. My calculations say a 10 x 14 hem fir wood beam will work.
JA: OK. Is there anything else important you think the Structural Engineer should know?

Expert:  StructuralEng replied 1 month ago.

I apologize for the technical difficulty. I posted a some questions a few days ago, but it looks like they didn't go through.

Do you know the ratio of LL to DL?

Do you have any deflection limits on the beam?
