AirPlane on a Teardmill and Mythbusters

Dude, this is not a "relative motion" issue, at least not in the sense that you are implying. The plane, its wings, and it's wheels are all moving forward at the same speed relative to the air around it. What is happening on the ground has no affect on the speed in relation to the stationary air air molecules, which are not on the treadmill and not moving backward.

EXACTLY!!
 
exactly read the last section of my response, the conveyor is acting as an infiintie tail wind

Your assumption here is flawed as well. The conveyor, if running towards the plane, is going to push air towards the plane if it were to move air at all..

You are either joking, or you are definitely not smarter than a 5th grader.

How is it not relative motion? The fuselage could be moving forward at 100mph relative to the conveyor, but develop zero wind speed. It could be moving forward at 100mph relative to the earth and develop 100mph wind speed ± prevailing winds. It could be moving 100mph relative to you traveling 65mph in the oposite direction which would mean that it is in reality only traveling 35mph. It could be moving 100mph relative to a person working on the runway jogging at 3mph in the same direction meaning its traveling 103mph.

The plane, its wings, and it's wheels are all moving forward at the same speed relative to the air around it.
Wait one freaking second right there, didn't you just say that this isn't a case of relative motion? Therefore, your argument is moot.

What is happening on the ground has no affect on the speed in relation to the stationary air air molecules, which are not on the treadmill and not moving backward.
but if the plane is "moving backwards" on the treadmill how can it generate airspeed?

Etc etc etc.

How can a smooth conveyor belt push air? It might create a small cushion of air on the surface, but not enough to create lift on wings. Now, if it was something like a snowmobile track with a means to actually move air thats a different story, but then the airplane wouldn't be able to use it as a runway.

edit:

I didn't say it was creating an infinite tail wind, I said it was "acting as an infinte tail wind" two completely different things.
 
hahaha those last two posts are fun :D:D what color is the plane...cause i think red is faster but black generates more power....white ones are more wind resistant

Did you know that a lot of professional card dealers can sense the difference between the red cards & the black just from the heat coming off the red cards??? it's true.
 
As for the wheels being powered or not...the wheels are not powered by a driveline therefore they free wheel.........they are NOT under power.
 
Two more days before supplicate tucks his tail and runs;)
psh, Mythbusters has usually messed up their experiments so bad that it doesn't matter anyway. Case in point, the exploding hammer.

Its as I said in a PM, it all depends on how its set up and executed. I can see it going either way, just having fun arguing the not taking off point to see just how different peoples arguments are. And sadly, there really aren't that many arguments. Seems that everyone else in this thread is simply looking at it one way without paying any regard to any of the other angles. This is why I repeatedly say that if the airplane achieves a net movement in the forward direction it can take off.

and again I say you are looking at the Macro picture, not hte micro picture. Look at something close enough and there comes a point where there is no distinction.
 
I understand that if you look at it a certain way, the conveyor is turning the wheels. It makes sense to me. That does seem to be sort of a philosophical way to look at it.

Does the tail wag the dog or the dog wag the tail?

I'm glad someone finally caught on to that.

When you get to a point with science it essentially becomes philosophy. And in philosophy 2+2 can = 5. Basic science only works if 2+2=4. There's always more then one way to look at it :D
 
This thread is like watching a monkey hump a football.

There's a lot going on, but not much happening. And THAT is philosophical way to look at THAT.

LOL
