Given: Total mass: 7500 kg
Centre of gravity (cg) location station: 80.5
Aft cg limit station: 79.5
How much cargo must be shifted from the aft cargo compartment at station 150 to the forward cargo compartment at station 30 in order to move the cg location to the aft limit?
The CG is currently to the rear of the AFT limit and needs to move forwards. This distance is 80.5 to 79.5 = 1
In order to move the CG into limits, we will need to move cargo from the aft compartment to the forward compartment.
Step 1. Establish the parameters:
m = mass to be moved (?)
M = total mass (7500 kg)
d = CG movement required (1)
D = relevant distance, between the compartments (distance between +150 and +30 = 120)
Step 2. Time for the formula:
m/M = d/D
m/7500 = 1/120
m = 62.5 kg
By moving 62.5 kg into the forward compartment, the CG is moved into limits.
