>>1312392If this is what you were asking-
If you’re trying to remove weight or shift weight. It’s just ( -weight x Arm -moment) from your final moment.
In my example. I started with a final Weight of 2,150lbs and Moment of 90,810. But I decided to remove the rear passenger. So I subtracted 50lbs from my final weight of 2,150. Then I also subtracted 3,650 from my final Moment. Which gives a finished- Weight of 2,100 and Moment of 87,160
The CG went from 42.23 to 41.50- therefor after removing the rear passenger the CG shifted forward 0.73 inches
