Re: Anser me this

I do not know.

I have not studied flight or anything to do with airplanes. I have no use for it.

I suspend judgment.

Re: Anser me this

>i agree, but that wasnt the question. "Imagine a 747 is sitting on a conveyor belt, as wide and long as a runway. The conveyor belt is designed to exactly match the speed of the wheels, moving in the opposite direction. Can the plane take off?" read the OP, NOOB

Damn it I'm too far into this to stop being trolled. It will take off because a 747 doesn't move by by turning it's wheels. It moves by pushing air. The conveyor could be going thousands of knots faster then the plane could ever go but as long as the air is stationary the plane will move forward relative to the ground next to the conveyor and take off in it's normal takeoff distance. Assuming the wheels don't explode from going that fast that is.

Re: Anser me this

you gotta be a troll, cant be this stupid. its not a matter of the conveyor slowing down the plane, its a matter that the wheels are unable to move forward without going faster then the conveyor. for the plane to move forward, it wouldnt be able to use wheels. a 747 cant take off without using its wheels.

Re: Anser me this

I give up. You are stupid. the wheels support the plane. The plane does not drive like a car. The wheels are free spinning. The engines/props move a plane.

Re: Anser me this

im not the moron that doesnt read the OP. i even quoted it to you twice. the question was if the conveyor was moving at the same speed of the wheels!  the wheels support the plane, the wheels have to be stationary or else they are moving faster then the conveyor. the plane cant get airborne while stationary, and it cant move without the wheels, so it cant happen.

Re: Anser me this

you're not thinking hard enough because i understand the part you're repeating excellantly "The plane does not drive like a car. The wheels are free spinning. The engines/props move a plane."

the problem is that the question was if the the conveyor moves as quickly as the WHEELS. when the engine/props move the plane forward, the conveyor is moving slower then the wheels are. for the plane to move forward, it must break the condition given in the first post. for the plane not to break the condition of the first post, it must be stationary. if its stationary it cant take off.

now instead of repeating yourself, because we both agree with what you're saying, say whats wrong with what im saying.

Re: Anser me this

With the tree example, it is staying in one place, as well as the air around it.

The air around the plane would be the same, there wont be any lift for the plane and no take off.

And IF it did lift off, which it wont, the plane would be in stall and would come crashing down anyways..

Re: Anser me this

The wheels and the conveyor can spin as fast or as slow at they want.  The wheels buffer the plane from the conveyor. The plane will still accelerate relative to the stationary air.

The plane will push against the air and move forward relative to the tree and will take off close to it's normall takeoff distance [relative] to the tree. The conveyor isn't holding the plane back since the plane is pushing against the air and not the conveyor.

The stationary plane is pushing against stationary air? tongue

Re: Anser me this

he is saying the conveyor doesnt impact the plane because as soon as it overcomes the friction, the plane will behave normally. what A10 doesnt understand is that the question wasnt if a plane could take off from a conveyor belt, its if it could take off from a conveyor belt that moves at the same speed as the wheels in oppositte directions. and the only way its possible for the conveyor and wheels to travel at the same speed in opposite directions when the wheels are on the conveyor is for the plane to stay stationary relative to the fictional tree that isnt ont he conveyor, and when the plane is stationary, it will not gain lift, and cant take off without the help of like a tornado.

Re: Anser me this

That means by the time the plane takes off the conveyor belt is moving at infinity does it not?

Re: Anser me this

The lift force which an aircraft needs to take off is as a result of air flowing over the wings.

If an aircraft is on a conveyor belt which means it is stationary with respect to an observer standing watching on a patch of grass next to the conveyor belt then the aircraft is also stationary with respect to the air around it. The air will not flow over the wings and therefore there will be no lift and no take off.

Don't need a degree in physics to realize that, problem is that people argue that the plane will ignore the belt and lift of like always

Re: Anser me this

I know you don't need a degree in physics to realise that, and that other people have written exactly the same as me but other people got ignored. I hoped that my degree in physics will lend some credibility to the fact that what I have written is correct. I was not bragging.
