Hello all, I should preface this by saying I'm about to start year 3 of my mechanical engineering degree so I'm still learning how to apply the principles I'm learning in school.

So, I'm interested in learning how to analyze the forces at the wing root when the wing has the Wittman style of wing-fuselage intersection, namely the "cuff" in the leading edge. The wing to fuselage mounting point on these designs places the forward spar wing root bolt below the neutral axis of the wing spar. It's my understanding that this will impose a bending moment on the spar.

My question is, how far out does this moment act? Does it only affect the spar from the wing-fuselage intersection out to the wing strut attach point? Hopefully this is a valid question..still learning here...
Thanks
