Avoid Aliasing when filming a moving car
Let's say $\omega_w$ is wheel rotational speed, $v$ is car speed, $r = 0.3m$ ($2\pi \cdot 0.3 = 1.88m = $ rolling circumference?) is the radius of the wheel and $f_s = 24Hz$ is the sampling frequency.

Then you need to sample an event with a period of $5\omega_w$ (stokes are indistinguishable from one another). Thus, $f_{max} = \frac{5\omega}{2\pi}$.

Then, by Nyquist:

\begin{equation}
f_s \gt 2f_{max} = \frac{2 \cdot 5\omega_w}{2\pi} = 5 \cdot \frac{v}{r \cdot \pi}
\end{equation}

Therefore:

\begin{equation}
v \lt \frac{fs \cdot r \cdot \pi}{5} = \frac{24 \cdot 0.3 \cdot \pi}{5} \approx 4.52 m/s \approx 16.28 km/h
\end{equation}
