Figure 2-6. Geometry of the front-rear inclination
In order to explain (21)- (23) using geometry and ratio and proportion, we can take moments about 0 in Fig. 2-6,
![]()
where:
![]()
Therefore: ![]()
Accordingly:

This equation compares well with Eq.(21).
Also:

which compares well with Eq.(22).
If intersection point of the line joining A' and G and the plane on which R1 and R4 lie is represented as S(Sx,y, Sz),then:
![]()
Therefore:
![]()
With Rr as the reaction total force on the rear wheel,

If we take moment about the contact point of the left rear wheel:

Similarly:
