Would the plane take off?

[bleachit]

THE PLANE WILL FLY! THE PLANE WILL FLY!! THE PLANE WILL FLY!!!

Anybody not get that yet? Do I need to repeat it? You, in the back? No?


THE PLANE WILL FLY! THE PLANE WILL FLY!! THE PLANE WILL FLY!!!

Any more questions? Anyone? Buehler? Buehler? Buehler?

wait a minute... I disagree....



you say the plane will fly? but the mill.. or tread.... thermodynamics..... what if the treadmill got some grass on it from when they mowed the lawn?

maybe it COULD fly if it was one of those airplanes with the pointy noses... but the fat round ones... not a chance in hell.




DIE THREAD DIE!!


its German for "The thread, the"

[LS1 WS6]

This thread has made me laugh so hard!! My first thought was that it would not fly. Then realizing ( as this thread has clearly pointed out) that the thrust and wheel motion is not related. The plane will fly. A car would go nowhere and a plane or something that is not wheel driven will move.

[Glickman]

NEITHER! you're all wrong!


the plane cannot take off cause it isnt moving , neither is the tredmill

Mmm.....Candy !!

[Will Wood]

Candy Buttons! Damnit.

That's what they were called.
I was so having an in depth discussion with my classmates the other week trying to remember what they were called.

No. Take-off is dependant on the lift produced by air moving over the wings at high speed. the speed at which the wheels are moving is irrelevant.

There is the correct answer.

[Alpha]

I be pilot...

its kind of tricky, but this is what would happen:

as the jets increase their thrust the plane would speed further down the conveyor belt until it reaches its Vr speed, or speed in which the plane will take off

/the belt has no effect on creating the lift
//tires would be doubling in speed...possible failure
/// would need a conveyor belt as long as the normal runway
////picture a kid wearing a jet pack and roller blades on a treadmill

Too bad the treadmill can put out the same speed as the jet pack can put out in thrust.

Its obvious that the plane could not take off. Relative to the AIR, there is no movement. period. The control system on the conveyor is responcible for this.

Do we all agree that the plane, relative to a fixed point in the air, is NOT moving.

Also, the plane, relative to the ground outside the conveyor runway is NOT moving.

There is NO air moving over the wing, considering there is no wind.

Lift is generated because air over the top of the wing is lower pressue then the air below the wing.

The air pressure is equal right now, because no air is movign over it.

Lift is not generated.

You guys are looking at the wheels as if the wheels create lift. It doesnt matter how fast they are going (unless of course you look at the speed at which they break).

Someone needs to make an animation.

If that was true, then the plane would not lift off. I believe the idea of the problem is that the entire plane is not moving



What about if it had props

No we do not agree on that or else we would not think the plane would fly. As has been illustrated in various examples because the plane does not depend on anything that touches the ground to for movement (traction) the treadmill will have little to no effect on it (some bearing resistance, but really not enough to matter once thrust is applied). The plane will move relative to the air around it, the stationary ground, etc.

good thing that link was posted 4 pages ago....

Why is this even being debated any more!!! Good lord people. Go back and read the past 5 pages of posts and then if you still think the plane won't fly smack/punch yourself in the: face, nose, nuts, or combination thereof.

Careful... This guy's from NASA.

You guys are looking at the wheels as if the wheels create lift. It doesnt matter how fast they are going.....

And YOU are looking at it, as if the wheels supply forward motion....THEY DON'T/CAN'T/WON'T!

The engines are going to accelerate to take off speed regardless of what the wheels are doing. The plane has no choice but to follow the engines into the air.

OMG !!

So much wrong there I don't even know where to start...........

[RRfireblade]

Anyone want to point out where in this picture is the Jet engines attached by drivetrain or transmission to the wheel?


Last attempt:

Matchbox car....

Treadmill going 50MPH...

You , holding the matchbox car in your hand, touch the wheels of the car to the moving tread mill....

Does the treadmill rip the car out of your and throw it backwards at 50 mph?

Umm.....no.

Why do you you think is?

Furthermore...

Your holding the car on the treadmill while the wheel are now spinning at teh speed of the tread mill....can you push the car forward on the treadmill?

Umm...yeah.

Why do you think this is?

Now:

Your Hand = Jet Engines abilty to push the car forward.

Anyone still lost on this subject needs to stop posting and go back to kindergarden and start over.
