Mass and Balance Question
Hi everyone A mass and balance question I need help with!
At a given mass the CG position is at 15% MAC. If the leading edge of MAC is at a position 625.6 inches aft of the datum and the MAC is given as 134.5 inches determine the position of the CG in relation to the datum.
Withn the answer it states -
The MAC is 134.5" long. The CG is 15% of this distance back from the leading edge. 15% of 134.5" is 20.17".
The leading edge of the MAC is 625.6" aft of the datum, the CG is 625.6 + 20.17 = 645.77" aft.
WHERE DO THEY GET 20.17 from!!
Or am I just being DUMB!
