I do have to admit, you personally created the thread that caused me to "miss" out on the most work ever, during the work week.

I'm afraid if you and I ate dinner together we'd argue over whether or not a plane with its wheels spinning on a treadmill could take off.
My face was like this: :spock: reading that thread. I had no idea what was going on.

Frazod 08-25-2009 03:59 PM
I'll limit this to people I haven't met:

Guru
JOhn
Flopnuts
Dane
Hamas

There's more, but that's the first five I thought of.

Then they did not use the same criteria described above.

If the planes wheels are spinning, then the aircraft has no relative ground speed. If if has no relative ground speed, no air is flowing over the aircraft's wings. If no air is flowing over the wings, there is no lift. If there is no lift, the plane will not fly.

Any of the following would be cool.

Gonzo, Pestilence, Sofa King, Flopnuts, Hamas, Admiral Crunch (Crush I think?), Buzz, D2112, Frazod, Fritz88, Gadzooks, Goapics1 (apics1), joey (I think hes in prison), Nzoner, Oceanic815Survivor, Simplex3, Smed1065, Sure-Oz, TinyEvel, and xbarretx

Those are all the people that are on my friends list...except Pestilence, wtf man?

Also if you are like top 25 in rep score that'd be cool too. Now rep it up bitches!

Oh, also anyone who watches the Wire or Lost.

Off the top of my head: Reaper16, Brock, UP, KcMizzou (?), Baby Lee (both - superbadass) , keg in kc (both), ZootedGranny, Miles, irishjayhawk (he watches both I think, so hes super badass), SportsRacer, DaneMcCloud, arrowheadnation, BigRedChief, and the last one I can think of is Red_brooklyn (I think thats his name, not sure).
Nobody can truly narrow it down to only 5 people. Don't worry about it. There are others I want to meet just as much as my five too which is why I just said everyone.

this is one of the reasons I always hit Joe's Bash now. Every year I meet somebody new.

I'd have dinner with anyone who wants to have dinner with me. Which, in this case, none.

With that said, I'd honestly have dinner with any Chiefs fan who doesn't drink all my liquor, throw up on my couch, rape my dog, and end up on the roof naked and having incoherent conversations with Jesus of the eternal moonlight.

If you can behave like a gentleman, provide engaging and intelligent conversation, not trash my jazz collection, and drink like an old man going over the hill singing, then you're all right at my table. For the chicks, you're all invited as long as you're topless and don't talk much. :D

I always thought the treadmill would be going the opposite way of the plane's forward motion (or attempt at motion).

So ignoring friction, if the planes wheels were just spinning, and the plane remained still relative to the ground, and then the propellers turned on and spun fast enough (theoretically), that would not create enough lift for the plane to take off?

That would only make sense if the plane were being propelled by its wheels. And even then, you could still take off (in theory) if the wheels are moving more quickly than the treadmill.

No, it would not. Air flowing over the wing creates lift. However, if you ever played with a rubber band aircraft, you'll remember that if you really cranked the rubber band up, you could hold the plane with the propeller facing the sky and the propeller would create enough lift (briefly) for the plane to increase altitude. Not unlike a helicopter's rotor.

If the wheels were moving more quickly than the treadmill, then there is some other motive force being applied (say a propeller). The simple fact is that without sufficient airflow over the wings, teh wings aren't going to produce lift.

Of course, a plane's wing can produce sufficient lift for take-off if a gust of wind flows over it at the velocity for take-off.

Yes, I just watched it. You'll note that the plane was moving relative to the ground, which of course caused air to flow over the wings and produced the requisite lift.

I guess if the you could say if a plane is not moving forward relative to the ground then it cannot take off. But I thought the question was worded saying if the wheels were spinning at the same rate as the conveyor belt.

Because it is not an accurate test of the theory, as I said earlier. If the plane's wheels are not locked and free to spin, the treadmill underneath the plane would simply spin the plane's wheels and the plane would not move forward at all. If the plane is not moving forward (that's how planes generate enough speed to move enough air over the wings to produce lift), the plane will not take-off.

Perhaps I'm misunderstanding what you're arguing (like everyone else apparently). Are you saying that a treadmill couldn't essentially "launch" the plane by moving in the same direction because the wheels would spin and the plane wouldn't move? That's a very different argument than the one I think everyone else is talking about - that a plane could take off under its own power while a treadmill was under it and moving in the opposite direction.

No, I don't, because the theoretical test and the one Mythbusters performed were not the same. In the case of the treadmill, the wheels are only spinning because the treadmill is moving underneath them. In the Mythbusters test, the plane is moving forward relative to the ground. So, of course the wheels are spinning, but they are spinning because the aircraft itself is moving, which wouldn't happen in the above scenario.

I'm saying that a plane sitting on a treadmill with its wheels unlock and free to spin would not take-off if the treadmill were accelerated to a speed normally required for lift-off.

Me neither, but his answers make a whole lot more sense when you realize what hes arguing.

Pretty much the wheels could be moving forward at lets say 50 mph, while the treadmill moves backwards at 50 mph, but that doesn't mean the airplane is stagnant, its still moving forward.

I don't know why I'm still going.

If the plane had a rolling start, then the treadmill caught up to the speed of the wheels, technically the wheels and treadmill could be moving at the exact opposite velocity of eachother, yet the plane would still be moving forward due to momentum, right?

I may have confused people by mentioning the wheels, but I did so for good reason. If the wheels were locked and the treadmill accelerated to lift-off speed (and the plane didn't slide off or skid), then the plane would fly, becuase it achieved enough forward velocity to provide sufficient lift for flight. Essentially a catapult.

If the wheel are free to spin, the plane would not move at all and therefore the wings would produce no lift.

I was assuming the treadmill was going the opposite direction of the way the plane was trying to go.

Baby Lee 08-25-2009 04:59 PM
ROFL - some sites have banned all discussion of the AoaT question. The fundamental ambiguity at the heart of the controversy is below.

http://blag.xkcd.com/2008/09/09/the-...amn-treadmill/

http://imgs.xkcd.com/blag/treadmill_diagram.png

Quote:
2. vC=vW: That is, if the axle is moving forward (relative to the ground, not the treadmill) at 5 m/s, the treadmill moves backward at 5 m/s. This is physically plausible. All it means is that the wheels will spin twice as fast as normal, but that won’t stop the plane from taking off. People who subscribe to this interpretation tend to assume the people who disagree with them think airplanes are powered by their wheels.

3. vC=vW+vB: What if we hook up a speedometer to the wheel, and make the treadmill spin backward as fast as the speedometer says the plane is going forward? Then the “speedometer speed” would be vW+vB — the relative speed of the wheel over the treadmill. This is, for example, how a car-on–a-treadmill setup would work. This is the assumption that most of the ’stationary plane’ people subscribe to. The problem with this is that it’s an ill-defined system. For non-slip tires, vB=vC. So vC=vW+vC. If we make vW positive, there is no value vC can take to make the equation true. (For those stubbornly clinging to vestiges of reality, in a system where the treadmill responds via a PID controller, the result would be the treadmill quickly spinning up to infinity.) So, in this system, the plane cannot have a nonzero speed. (We’ll call this the “JetBlue” scenario.)

But if we push with the engines, what happens? The terms of the problem tell us that the plane cannot have a nonzero speed, but there’s no physical mechanism that would plausibly make this happen. The treadmill could spin the wheels, but the acceleration would destroy them before it stopped the plane. The problem is basically asking “what happens if you take a plane that can’t move and move it?” It might intrigue literary critics, but it’s a poor physics question.
So basically, those in the 'won't fly' camp read the conditions to require that the axle -->wheel -->airplance have no forward momentum, otherwise the treadmill isn't actually 'mirroring' the airplane's efforts. They aren't concerned with the practical side, where the jet engines will accelerate the wheel/treadmill apparatus to infinite speed [not fast, not really fast, but infinite, as in increasing exponentially without end], and the system fails.

DUDE. Donger. If you put a plane on a treadmill and engaged the engine, it will create thrust and move the body of the plane, regardless of WTF the wheels are doing, off of the treadmill, and take the fugg off.

The plane DOES NOT get it's speed from the wheels. It gets it from thrust created by the engines (prop, turbo prop, or jet, typically). When the engines are engaged, the wheels would just spin faster than the treadmill and taxi off.

If the plane had a rolling start, then the treadmill caught up to the speed of the wheels, technically the wheels and treadmill could be moving at the exact opposite velocity of eachother, yet the plane would still be moving forward due to momentum, right?
It would immediately begin to decelerate until its ground speed became zero. It's the same basic concept as DaFace's scenario above:

"that a plane could take off under its own power while a treadmill was under it and moving in the opposite direction"

In that scenario, the forward motion of the plane is precisely the opposite of the force being applied by the treadmill. Therefore, they cancel each other and the relative ground speed of the plane is zero = no lift = no flight.

btw, you want to kick someone in the shin?

with a little better aim you could kick their family jewels into the next county...

as for pompous, how long have you been around here?

Yes, we've established what is required to produce lift.

Don't be an ass. That is what will happen regardless of what the wheels are doing. Another good example is that the wheels will move at a slower speed with a tailwind, which illustrates that it doesn't matter what the wheels do. If the engines are creating enough thrust to creade lift, the ****er's flying.

Baby Lee articulated it much more effectively than I did.

As far as the OP, its too hard of a question. Too many good posters here.

Actually, the wheels in the treadmill scenario are very important. As I said, if the wheels are locked, then the treadmill basically acts as a catapult. The plane would quickly achieve sufficient ground speed (or air speed over the wings, if you prefer) required to achieve lift and flight. If the wheels are free to spin, that makes thing a bit more complicated.

The wheels don't matter. The thrust does.

You need to read Baby Lee's post.

If the wheels are locked and the treadmill moves, the wheels most certainly do matter. Because the plane will move in the direction the treadmill is moving, regardless of any other motive force.

Look at it this way:

A plane is sitting on a treadmill

The wheels are free to spin.

The plane's propeller is not moving (so it has no forward thrust).

The treadmill begins to move in the direction opposite the plane's normal direction (forward).

In that scenario (and assuming a lack of friction), what would happen to the plane?
