Case II.

 

Case II.  and

 

Same as in Case II, a slip ratio due to the critical value of the slip ratio can be obtained as:

 

                                                  (1)

 

A slip ratio due to the critical value of the slip angle can be found as:

 

                               (2)

 

When

 

The nondimensional slip ratio , is determined as:

 

                                           (3)

 

where,

 

 

The nondimensional contact patch length  is found from the equation, and the modified lateral friction coefficient  is expressed as:

 

                                        (4)

 

For the longitudinal force, the lateral force, and the self-aligning torque two sub-cases should also be considered separately. A slip ratio due to the critical value of the inclination angle is not needed here since the required condition for Case II, , replaces the critical condition of the inclination angle.
