Which way joists?
In my garage I am trying to figure out which way the joists are running. It looks almost like they run differently on either side of the support but I am not sure. I have included a photo to help. The peak of the roof in to the left of the support but the spackling runs different as you can see.
Help appreciated in advance.
Thank you

I'll agree the back room seems to be running left to right while the fore room is perpendicular, and that's according to the sheetrock screw pattern. The long runs of mud are the factory edge of the sheetrock.

I think it looks like the run was longer than the sheetrock they used so the area near the beam was patched in.
Sure looks like the joist just run at a right angle to the beam and sit on top of it.

I'm not an expert, but isn't the reason the long support exists (going from left to right) is to hold up the joists? ...the joists must be resting on it.
Another way to verify is to remove the plate from the electrical outlet and pry around using a flashlight. Electrical boxes are fastened against a 2x4/6/8 the long way, so that electrical outlet confirms the joists are perpendicular to the long support (girder).
Another clue: I see the springs of the garage doors and this tells me which way the garage bay is running and garages are at least 20 feet deep. At 20 feet deep, the joists cannot be running parallel with that long support since you'd need a 21 foot joists ...which would be insane.
Again, I don't see a reason to install that long support if the joists wouldn't rest on it. So I'd say it's there for a reason and all joists are perpendicular to it, but I'm not totally sure.

Good analogy, Tony BUT
Sheetrock is never hung parallel to joists, as would be evidenced in the near portion.
My guess is this is either a hip type roof or it has a change of direction, making the joists go 90 degrees to the others. Without seeing the roof system, it would be a guess, however.
