I am having a bit of trouble interpreting a detail. I've done what I think makes sense but would like some confirmation of my thoughts before proceeding.
The drawings are not quite clear as to whether or not these load struts are embedded into the ribs like I show here, or on centerline back to back, flat side to flat side.
I am favoring this only because it seems to make sense to transfer loads from longitudinal to longitudinal. Still, I have to wonder about a centerline mount with an appropriate backing plate???
