From what I’ve found on onshape, the distance between the eyebolts on the trusses is about 100 inches. A mentor and I also figured the distance to be about 100 inches via the field drawings and some geometry. I think saying “about 100 inches” is good enough to to the fact that chain moves when touched, so the chain won’t be very still on a playing field.
I figured I’d post this finding because it might be useful to teams who are trying to find that distance.
