Plane on a Conveyer Belt

This airs tonight right? I dont have cable stations, so I wont be able to see it, I will have to rely on a video later. I expect a link to the show so I can see it

If you would measure the WIND speed at the wing on the plane, there will be virtually no AIR MOVING OVER IT. How can it fly?

Why would you think there is no air moving over it? The plane will not stay stationary. The plane will move forward first and then fly.

If the conveyor belt is moving at the same speed AS THE PLANE, the plane will not move relative to a stationary object. Therfore, no air over the wings.

i just cant wait till tonight lol

Me too. It will show how lacking Floridas education is.

and will have to work twice as hard to get to take off speed

No it won't. Any friction is negligible and will have no impact on it's ability to move forward.

It will NOT take off.

think of it this way. Since the air is what a planes uses to move not the ground picture this.A car with 2 long bars going through it on each bar there is 4 people pushing the car in one direction. The car is in neutral, and on a conveyor belt. The people pushing the car are not on the belt and start pushing the car 5mph. Now start the conveyor belt to 5 mph and what happens? car keeps moving 5mph, the wheels are spinning 10mph but doesn't matter because the force is being created seperate from the conveyor. Like on a plane the wheels are in neutral and the air gets pulled through the propeller and forces the plane to move.

the wheels have the same velocity (direction and speed) as the conveyor belt

There will be wind. The plane will move forward.

The plane is a separate entity from the treadmill; they are not conencted in any way. The wheels are simply a ball bearing between the two.

A plane ability to move is not in any way determined by ground speed.

Go flow some nursery rhymes and let the big people talk.

A plane taking off on a conveyor belt will look identical to a plane taking off on a runaway.

Hence, you need a LONG conveyor belt.

I love everybody's comparisons to try to justify their position, and explain it to others that aren't seeing it their way... //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif "For Example, if you take a car with 2 bars... "For example, if you put a Hot Wheels car in a bathtub full of Pistachio pudding... "For example, let's say you take a room full of nuns having an orgy, but said room is on wheels..."

Jebus you guys. The plane will fly. Remember Top Gun? When they take off (in the opposite direction the ship is heading, I might add... SORT OF LIKE A ****ING TREADMILL), what do they do to propel the plane? Stop the ship??? Course not. They raise that thing behind the engines, so that thrust is enhanced and it moves the planes forward at a rapid rate. Why is this, you might wonder? Because planes operate off of THRUST. Thrust is generated by their engines and pushes against the wind, or air, or some object placed behind the engines, or what have you. So just because the plane is on the treadmill, doesn't mean that when the engines kick on, that all of the sudden the concept of thrust is out the window and it has to overcome the speed of the treadmill. Because it uses AIR. Not the friction between the tires and the treadmill. Picture the plane not moving at all, engines off, rolling backwards on the treadmill as it sits, stationary in relation to the treadmill, and moving backwards in relation to the ground. As soon as the engines turn on, the plane will propel forward, because of THRUST. It doesn't have to get its wheels up to speed to overcome the backward motion of the treadmill first.

man, you dont understand physics and you **** at haiku //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

not much of a math wizard but saying if the belt is moving at take off speed (idk lets say 120mph) and the plain was not started it would be moving backwards at 120 mph.(sounds stupid i know and probably wouldt sit still) but if the plain engine was started and got to take off speed (same as belt) it would become stationary like a hamster on a treadmill, moving but sationary. it would then need to accelerate to 220 to achieve a momentum or actual speed of 120 with relevance of air speed. i hope im being clear
