I think we can all agree that the plane will move at 20 mph backwards


no, i do not agree with this, because the wheels rotate INDE-FEKING-PENDENTLY of the motion of the aircraft. The conveyor will start up, and the wheels will spin, but the plane won't go anywhere. at least ideally... there is rolling friction which will make the plane go backwards, but it isn't the same thing you are talking about.

So in short, we all agree that it won't take off, right?

These engineers must live in Magic Crazy world or something.

If it took off why would we bother wwith runways or airports?

They won't asnwer that question though because the "take offers" are skeered.

What's your point?

We have airports and runways because it takes some distance to get the plane off. The plane will take off without a doubt. It doesnt matter how long your conveyor is.

I'm guessing the conveyor would have to be just as long as the runway would have been.

If they would take off why dont we just put the planes on conveyors - they could take off from anywhere.

We could probably land the plains on the conveyors too.

Better yet, just build the conveyor long enough so that you could just set the plane on it, chock the wheels, and ride the conveyor wherever it is you're going.

because conveyors are expensive and they have no effect on the airplane taking off.

We should build these things with tracks that go cross country - they could be powered by steam or coal - then we could cars on them.

They could carry cargo or people. I'm getting a patent on this idea.

You don't like dinosaurs and sharks?

and Goose...probably like this.

So flaith your telling me that a plane with the engines off on a conveyor belt would stand still.

in a frictionless environment, maybe, but this is reality.

of course it wouldn't stand still. i'm just talking idealized condit's here.

as soon as you turn the engines on to ANY power setting, the plane is moving forward.

So in your idealized conditions, do you agree that there exists a condition that the conveyor belt is moving, the engines are on producing some thrust (although very small) but the plane is sitting still?

In this universe, the plane will always move forward. Period. (Well, unless it's in a vacuum.)

In this universe that conveyor belt doesn't exist so it doesn't make any sense to confine the construct to this universe.

How does the conveyor belt not exists? There are conveyors out there that are plenty fast enough to keep up with the plane's speed. However, the conveyor speed has no effect on the plane moving forward (execpt for friction, which is negligible, unless it's moving at astronomical speeds).

It's not a matter of how fast it can go. It's a matter of the plane accelerating and the conveyor is ALREADY moving at that speed.

You're right. The conveyor will never be able to match the actual speed of the plane.

EDIT. On second thought, I'm not sure about this. The conveyor speed does not make a damn bit of difference either way.

A plane's acceleration is completely independent of wheel speed. The conveyor is moot.

Only if the wheels are frictionless.

Which means since we have a magical conveyor it all depends on whether or not we have magical wheels and how the conveyor is set up. If it merely matches WHEEL speed (or if the wheels are frictionless,) then of course the plane flies. But if the wheels are indestructible and the belt is set to travel at a speed to transfer enough force through the bearings to equal forward thrust then the plane sits there.

I have no idea how mythbusters is going to test this since none of these things exist.






BTW on a totally random tangent, on a scifi show someone once mentioned frictionless bedsheets.

Would it be possible to pick such an object up?
