Default Can a Plane on a Treadmill Take Off?

We aren't talking about the forces at work on the wheel or tire, we are
talking about the forward velocity. I can see this concept is lost on you.


There is no forward velocity - there *is* a change in angular momentum
though. Do you not understand that concept?


I proudly profess to not understand that a point on the top of a tire
does not move at twice the velocity of the axis of the wheel on which
that tire is mounted.
