You are correct (if you put your trailer into a no gravity zone (like outer space). You are my first alien contact on RV.Net.
If you would bring your trailer here on earth, gravity does do its bending thing, if you like it or not. In fact EVERYTHING on earth is bent (past tense), sometimes just bent into a straight line (I know, this will bend (present tense) your brain; double pun intended (yes, gravity bends even the stiffes brain on earth!).
This sounds like somebody educated beyond their intelligence, or acting stupid. Over the years I have bent a lot of steel, (most, but not all on purpose). I have had some sag under own weight when lifting 1 end.
But even a super light duty, like a garden cart, when loaded to capacity, you lift the tongue, the back goes down, but nothing bends. (If it did, you could not tow it without it bending.)
Who is talking about raising the tonque? if you raise or lower the tonque, the bending does not change (yes, it is bent if a load is applied). But if gravity is present, your tonque is actually pushing UP the A frame. If you want to test it (the amount of bend), balance out the trailer (for example put a lot of weight on the rear until the tonque just lifts up. Now check how much your rear has gone down. That is about the amount your front is sagging. Note: you would need to put jacks under the center (axles) to prevent your suspension to go down.
But the concept of a beam bending, the force that act upon the beam, bending stiffness, moment of inertia, forces from acceleration, etc is very much beyond the grasp of the most of the members of this forum, and not (I realize it finally) suited for discussion here.
