Hi,
Would someone mind explaining the answer for this one? I'm not sure if it's a calculation or some other method.
I can't figure out an answer form the explanation given.
Regards,
PJ.

Hi again,
Is someone able to check if I am getting the answer correctly here please?
Workings;
a) 2785 - 2360 = 114.75.
b) 2400+114.75 = 2514.75.
c) 2514.75 - 2400 = 165mm (Answer C in the question)

I thought I needed to take 2514.75mm from 2560mm at that GWT? I can get the answer given using 2400mm, but I'm confused as to if it's correct or not.
Regards,
PJ

Hi PJ,

One hint that I give students is to always label your answers to avoid confusion
FWD C of G calculations correct
(2785kg - 2360kg) X 0.27 = 114.75
So FWD C of G at 2785 kg is 2400mm + 114.75 = 2514.75mm
AFT C of G is always 2680mm
so the C of G range is AFT C of G minus FWD C of G, which is 2680 - 2514.75 = 165.25mm
