Alright..this has dragged on long enough.

No, the plane won't generate any lift. For the plane to stay on the theoretical treadmill, if would have to have it's engines going to match the speed of the treadmill (i.e. making it stationary). Because the treadmill only moves the wheels of the plane and not the entire column of air directly above the treadmill, there is no air passing beneath the wings and thus no lift.

If the plane were to exceed the speed of the treadmill and actually move forward, drawing air beneath the wings, then you'd have lift. But all that air moving under the wing just isn't there when it stays stationary on a treadmill. All that'd happen is a change of tires after a while.

sorry no

Why not?

Kszchroink · « **Reply #63 on:** October 06, 2007, 11:33:25 am »

think about the wheels

think about them

Smegma · « **Reply #64 on:** October 06, 2007, 11:35:11 am »

If you know the fucking answer, just tell us it.

Kszchroink · « **Reply #65 on:** October 06, 2007, 11:36:52 am »

no i'd like to see you figure it out yourselves

after that, another riddle!

Smegma · « **Reply #66 on:** October 06, 2007, 11:38:33 am »

Then tell us how the wheels fucking work, if you are going to give a hypothetical question people take many assumptions.

Kszchroink · « **Reply #67 on:** October 06, 2007, 11:43:18 am »

all i'm going to say is that they don't work like car wheels

Coming from the guy who made the obscurism threads.
"I already explained what I believe"
"No you *****ing didn't"
Anyway ksz, your just being retarded. It's not possible. Wheels have nothing to do with it, it is airflow.

you are a total dumbass, the wheels are just like car wheels, all they are for is for rolling it out and breaking when it lands.

I am going with 4yo here, unless you can give a detailed explanation on why the wheels are different also how lift can be generated while not moving you are just being an idiot/troll, should just be quiet and except the facts given.

Kszchroink · « **Reply #71 on:** October 06, 2007, 12:01:52 pm »

okay fine since you guys are being mean: the wheels generate no propulsion at all. the treadmill will make them spin but they don't affect the plane's movement at all (except for breaking when landing).

the turbines/propellers make it go forwards, the wheels are there to lessen the power needed for it to move

VJITCH ALREADY SAID THAT

Quote

Imagine an airplane standing on a gigantic treadmill. The plane is taking off, but the treadmill is moving in the opposite direction at the exact same speed. Would it still be able to lift off?

So, the plane must be using its engines to move, as vjitch said, or else the treadmill will not be moving!

Damn, learn to read.

brosef, the plane would move, treadmill or not

nice "learn to read" burn though

Thanks Cap'n Obvious!

Geo is right, mostly because he agrees with me but also because he understands physics more then the vast majority of the people in this topic

Kszcholugsdkhink: you don't even know what lift is, now don't make me get all wikipedia on your ass.

god damnit guys i'm taking the effort to use text formatting for this post

THE ENGINES WILL GENERATE THRUST AND PUSH THE AIRPLANE FORWARD
AIRPLANE WHEELS SPIN FREELY

LtKillroy · « **Reply #78 on:** October 06, 2007, 12:16:37 pm »

I still don't see how ksz's arguement supports the plane would fly. I don't see why this thread is still here, all were answered.
