These equations compare will with (19) and (29). Similarly, for (17) and (18), equivalent equations can be derived. return
Sample problem:
At what inclination angle will there be a slip off?
Solution:
Sample problem:
At what inclination angle will there be a turn-over?
Solution:
When RAz is set equal to zero, from (14),
Therefore:
Sample problem:
For a lateral turn to occur about the line joining A' and the contact point of the left rear wheel, what is the value of f?
Solution:
From Eq.(19), when R1z=0:
Therefore:
Sample problem:
Under what condition will the above lateral turn occur?
Solution:
From Eq.(23): 
Therefore:
