QUESTION
I understand that in aft swept wings the load is higher on the inboard portion of the rear spar than on that of the front spar. Whilst this intuitively makes sense, I can’t really explain to myself why and would be thankful for clarifications. I am also unsure whether this effect is more to do with the geometry or with the fact that the load on a wing is not uniform.

The reason is probably that with a swept wing the rear spar, being the shorter, stiffer element, and, therefore, load path, will experience larger internal loads than the front spar.
