Frame Analysis Using Method of Members. Determine the force in bar BE. 2. Well, I don't know where to start. I know there are three equations EFy=0, EFx=0, EMc=0 but I don't know what the first member to consider and how to solve this type of problem. There is a final answer given, BE = 2410 lb (Compression) I am trying to isolate the left and right trusses. Is that the right thing to do? Please help, Thanks!
