I agree with snigs' answer.
Formula is :-
Weight to be moved = (total mass) times (distance CofG is to move) divided by (distance weight is to be moved)
w = (10650) * (172 - 165) / ( 210 - 94)
w= 642.6724lb
Jinkster, looking back at your mail you have the correct formula, but the wrong answer. Time to change the batteries in your calculator
