Calculating the X-coordinate of the Centre of Gravity
Fig. 8-191 SPBGA21_004 Calculating the X-coordinate of the centre of Gravity
Table 1-192 SPBTA22_003 Terms used in this calculation
Knowing the value of the wheelbase WB, and the axle loads obtained by weighing
the vehicle LF and LR it is possible to calculate the position in X of the centre of
gravity.

NOTICE
The Centre of Gravity must be maintained within the wheelbase at all times.
Otherwise, it might negatively impact vehicle behavior on the road.
