….. is wrong!.

Explain how.

I got to admit. I can't figure out what you are saying. Willing to entertain the idea though if you want to re-phrase.


If the wheels were imovable, as they would be if Angular Force of wheel = Linear Force of Conveyor, wouldn't the force being applied by the engine, cause the plane to rotate about the fulcrum (Wheel axle)….

I'm pretty sure he's saying that the plane will do a front flip.

or a barrel roll, or somesorta spinni-ma-jig move.

edit: beaten. damn me for getting up and going to the washroom mid-posting.

But.. won't relativistic effect some into play as the wheels approach the speed of light?

The mass increases as you approach the speed of light, so you never get higher than it. All speeds remain finite.

I had already noticed that and edited my reply.

All others…. I'm going to go ride my bike now. It's been a slice, and I'll play later.
but briefly….

jbazzet: nice drawing, I understand, but I don't understand the part about the wheels being immoble. (I apologize if I'm totally missed your point.)

Chup: I've previsouly defined two method of measuring speed of wheels. I've also given an argument why rotational speed doesn't fit within the constraints of the rest of the question. I can try to explain further, but I think that's the crux of the whole thing.

and, yes - I realize I'll probably never convince anyone. but it is fun.

First, why not just say "speed of the plane". Second, when people talk about wheel speed, they are talking about how fast the tires are rotating, and not about how fast the axle is moving relative to the ground.

I think "speed of the wheels" was put into the question on purpose, and it had it's obvious effect.
