I can also prove that 1 + 1 = 10 :wink:
I'd like to see that proof. I've seen one similar to that before, but it divides by zero and only Chuck Norris can do that.

So basically the question is "will a plane on a treadmill take off?" The answer is no. No forward motion = no change in pressure = no lift.
Well, you see there is this 300 post thread on CF...

There are 10 kinds of people in this world - those that understand binary and those that don't...
If you understand this quote, then you will understand how 1 + 1 = 10:

Why won't there be forward motion?
I'm sure somebody somewhere could devise an ideal treadmill that could prevent a plane from taking off. I could also devise a static runway that would prevent a plane from taking off. By covering the runway with rocks, dirt, mud, sand, etc., I could develop enough rolling resistance to counteract the thrust of the plane's engines and prevent the plane from reaching takeoff speed.
It seems to me that the question being asked is whether a covnetional airplane on a conventional treadmill/conveyer would take off. Using a model airplane, we certainly have conveyor systems large enough to test the scenario. And the answer is yes, the plane will take off because conventional treadmills are not designed to impart a rolling resistance large enough to oppose the thrust of the planes engines.
And that is exactly my point. The question is - given (an ideal) treadmill, will a plane takeoff.
Shhh, don't tell Jeremy.Are you guys still talking about this? This seems like the never ending thread V4.

What is an ideal treadmill? Is it an ideal device for preventing an airplane from taking off? Or is it an ideal device for human exercise? These are different devices, and they would be designed differently. There is no single ideal multipurpose treadmill.
Somehow, I think that when the person first pondered this question, that person probably wasn't thinking about the plane-stopping treadmill, but more likely was thinking about the human exercise treadmill...
At least it's on topic - or rather has a topic.

...........You are all crazy. The plane is not moving!! Only the wheels are. No movement, not lift!! Freaks!
So basically the question is "will a plane on a treadmill take off?" The answer is no. No forward motion = no change in pressure = no lift.
Some are deviating from the actual question and concentrating more on the non-realism of creating such a treadmill. The two issues don't answer the same question.
Can such a treadmill be created and contain the aircraft? Probably not. But that's not the point of the question.
