good explainations.
Note that the tongue weight does NOT change. forces change and hence the force on the axles changes, but tongue weight does not change.
Think of it this way. you stand on a scale. Opps, I need to loose 10 lbs, so I push down on the counter next to it and the scale drops 10 lbs. Wow, easy way to loose weight! No you didn't loose any weight, but you now have a 10lb opposing force dropping a force of 10lbs off the scale reading but putting 10lbs on the countertop. total forces didn't change, nor did weight, just how the forces are distributed.
Or a wheelbarrow full of stuff. As you lift up the arms, you feel the force on your feet, and some goes to the wheelbarrow front wheel, moving force from the wheelbarrow legs. but if you and the wheelbarrow were on a scale, the scale doesn't change. Nor does the sum of all the forces.
While the term WD is a good marketing term, the reality is that these hitches are really a FORCE distributing hitch. The force distribution changes the forces (weights) on various points but does not change the actual system weight nor total system forces.
