The automobile steered by an Ackerman mechanism has the schematics below. According to the author (Reza N Sazar, Vehicle Dynamics: Theory and Application), the steering angles must not violate the relation below.
\begin{equation} \cot{\delta_o} - \cot{\delta_i} = \frac{w}{L} \end{equation}
However, the book is not explicit about the relation between $\omega_i$ and $\omega_o$. I would like to request some help from you fellows. Any help is sincerely thanked.
