First, if you want to install an axle on the wheel, and then install a load on the axle, the requirement for the wheel at this time is that the distance from the axis to the edge is equal everywhere, so you can't use Leroy triangle as the wheel;

Secondly, if the platform is moved directly on the wheel, the distance of each straight line passing through the center is required to be equal, so Leroy triangle can be used as the wheel.

Note: The second requirement is actually more relaxed than the first one. Whether you can make a wheel depends mainly on which working mode. Different premises lead to different conclusions.

Pure hands, hope to adopt, thank you ~
