If the conveyor is moving the same way as the plane will it take off? YES. Are the wheels turning? NO. I will say it again: NO THRUST IS BEING APPLIED TO THE WHEELS. The wheels are not a requirement to allow the plane to become airborn. The wheel speed is not a relevent point. It is only put in there to confuse people. Far as there being no breeze, so what? An airplane does provide its own airflow over the wings to provide lift. THEREFORE IT WILL TAKE OFF.

The airplane cannot move forward without the wheels moving forward, can it?

The airplane doesn't make its own lift if it isn't moving, and it cannot move forward if the wheels are not moving forward. The conveyer will hold the wheels back, and the wheels will hold the airplane back. And it cannot take off.

IT CANNOT TAKE OFF.

IT WILL NOT TAKE OFF.

Why are you yelling? Why can't you just talk about this?

This is not a debate to see who can yell the loudest. This is a physics debate.

Well I guess some people don't want to listen to reasoning!!!
I guess I will just let you think what you want. Oh well, have fun with it.

Mn Tom is rite. Think abought it. If a air plain jet powered or prop powered is on a runway what moves it down the runway to take off?? The propulsion provided buy the jet or props. The wheels are just along for the ride. There sole perpose is to keep the belly of the plain off the ground. If there was a conveyor belt under the wheels going in the oposite direction at the exact eqaul speed of the plain the tires would simply be moving twice as fast as the plain. the propultion DOES NOT come from the tires therefore it WILL take off in exactly the same distance as if it where on a regular runway. Again there is no proulsion provided buy the tires. The tires will simply be spinning twice as fast as if the plain where on a regualr runway.

How is there lift if the airplane is stationary? There isn't. There can't be.

Can an airplane take off with no lift? No it can't.

Problem solved.




10 MPH. (Did you type that one wrong, or are you being sarcastic?)
Wrong on both acounts. 1st the conveyor belt is nothing like a dyno. A dyno spins because of the power going to it buy the wheeles of the vehicle on it. Teh wheels of the vehicle are what provide the propultion. The wheels of the air plain do nothing but hold the plain off the ground when it is not in the air. The propultion is provided buy the jets or props not at all in contact with the ground or in this case the conveyor belt. The plain will move forward just the same as if it where on a runway. The only diference is that the tires will be moving twice as fast as the plain. Think of it this way, If you took a match box car and pretended your arm was the props or jet propultion system. If you put it on the table and push it as hard as you can WITHOUT letting go the car will move at what ever speed you can manage to move your arm. The same is true for air plains. They will move at waht ever speed the propultion devise(jets or props) is capable of pushing the plain. Now imagine you took that same mach box car and put it on a belt sander that was laying horizontal(flat). The sander represents our conveyor belt for this exercise. If you took the same machbox car and put it on the sander and pushed it as fast as you could in the oposite direction the belt sander was turning, with out letting go the car would move at exactly the same speed forward it did on your kitchen table becaus the propultion was coming from your arm not the tires on the belt sander/conveyor belt. Teh only diference is that the tires would be spinning faster than they where on your kitchen table. The propultion IS NOT provided buy teh tires that are in contact with the conveyor belt/belt sander it is provided buy the jet or props/your arm. Teh ONLY diference is that the tires are spinning at twice the speed as normal onthe plain /conveyor question.

Now for the Dozer question. The bottom ofhte track is not moving at all. 0 MPH. Picture a moving dozer in your mind. The top of the treack is moving forward twice as fast as the dozer is moving forward. Once the track touches the ground it is no longer moving at all. It sits stationary till the back wheel of the dozer goes over it and it starts to go around the back wheel. Then it is moved to the front of the system to be put back under the machine. When it goes across the top it is moving at twice the speed of the machine.
Never mind. sory beagle dident read threw all 26 pages of posts. i just found the one though where you changesd your mind already. I will leave the post up though as my argument as to why it will take off.

The plane almost lifted off and got caught in a high-tension power line.

Are you guys happy now?...........

I guess you didn't read all 26 pages, because I've changed my mind twice, and the first time I changed my mind I refuted my first post in much the same way you did now... (Oh, on edit I realize what you meant; my bad...)

The airplane wheels are along for the ride. But they can also hold the airplane back. The airplane, consisting of wheel carriage and engines, tries to accelerate as a whole. The whole gets held back because the wheels are being pushed back as fast as they are getting pushed forward. Eventually the friction inside of the axle equals the thrust from the engines, and the plane remains stationary.


Although I do not understand why I am making new arguments when it's impossible to refute my previous argument:

And so, contrary to Geico's wishes, THE AIRPLANE WILL NOT TAKE OFF.

All right, for those of you who think it won't fly, I have an easier question. See if you can get this one right.
If you had a submarine in a large bathtub - When the submarine submerges does the water level go up? down? or stay the same?

Re: bulldozer tracks - would you say the bottom of a tire in contact with the road is not moving?

water level stays the same. Because the sub has to take on water to submerge.

WHAT???? You are trying to say that the friction in the wheel bearings is suficant to hold back the air plain. I think not. the wheels will simply be sping twice as fast as if it where on a stationary runway. The air plain will still be moving forward as the conveyor belt ONLY has an efect on the speed of the wheels not the body of the plain. if what you are saying where try ball bearings would not function. On top of that if it where a fixed landing gear plain it would imediatly crash upon tak off because the tires where no longer spinning at the same speed the plain is travaling. If what you are saying is true then a air plain can only go so fast on the runway because the friction in the wheel bearings would be more than the thrust of the plain can overcome. So all plains would have to take off at the same speed or at least not above a certain speed because the bearings in the spindle would keep them from going above that speed on the runway. Sorry but WRONG.

That looks like one of my landings!

But the plane actually DID lift off!
