In the case of asymmetric thrust, the position of the CG does affect the required forces does it not ?
I’m afraid not. All that matters is that the moments (about the vertical) tally up to a grand total of zero.
If that is correct then while shifting the CoG you will have to change the forces.
Milt,
“now”? You’ll be hard pressed to find a post in which I disagreed with the irrelevance of the position of the CoG as far as unaccelerated lateral stability goes.
Any moment applied to a rigid body will, however, strive to rotate it about the CoG. Of course there tends to be numerous other constraints making sure that we get translation as well.
