I love lamp.
noone is taking into account how many passengers are on the plane. minglor you are totally right. too many variables like brand of tire, wether or not the plane has been waxed for least air resistance, how much coffee is in the courtesy wagon.
c’mon people lets get it right. silly diagrams just arent going to cut it. you OBVIOUSLY need to go back to school.
btw walter very nicely done, i think it proves this perfectly
I fly airplanes, and I know physics, and the plane will take off, the only ties of the plane to a tread mill movind forward, backward or mach 6 is the wheel bearing resistance, and any plane can overcome this easily.
ok im taking out the R/C plane and treadmill… vids later
lollerskates
I’ve always said it would take off
I so wanted to do the same thing last night just to / that thread, but i dont own a treadmill or a R/C plane so… Patiently awaiting vid of what we know will happen
you tie a plane up and give it the end of its rope… it will still take off… although i was skeptical with the harley design… the PLANE WILL FLY… crazyiness
Sad that the original post was closed >.>;
Anyways, my answer is no.
Explaination:
Objects can only move in motion when there is a force that acts up on it.
There are 4 forces in play: A (gravity), B (Lift), C (Forward motion by an airplane), and D (the counter force of C by the conveyor belt).
In order for the plane to take off, then the following has to be true: B > A.
For lift to occur, a (the air pressure under the foil of a wing) has to be greater than b (air pressure over the wing).
With every speed that the engine provides for forward motion, it is countered by the opposite motion of the conveyorbelt. Since the forward motion (in relation to the stationary object eg. viewer of a plane, standing next to the conveyor belt but not on it) is negated by the counter motion of the conveyor belt, the two forces cancel each other out.
There is no lift since the plane will never reach a speed that will allow the air under the wing to reach a pressure greater than over the wing.
Others on different forums have only debated that the positioning of the prop/jet can cause a slight different result. If the engine is placed in front (puller setup) then their a possiblity of air or pressure change occuring with the wing. This could cause lift. If the prop/jet is placed behind the wings, towards the back of the plane, then there is absolutely no change to the airpressure on the wings (granted the engines are not placed in proximity or flow path of wings)
Wow, this has been beat to death. It will fly.
^ flawed. The conveyor belt doesn’t exert enough force to counter the motion of the plane.
*post meant for raven, not Juiced. 
are you jokeing, or are you still trying to argue that it wont work?
I don’t see how a plane with no forward motion can attain lift.
I guess the only arguement that it will lift is if the plane can reach a speed greater than the wheels attached it. . .which is what I see people arguing, but doesn’t make sense.
If the plane reaches a speed greater than the wheels (dunno how 
) then the plane could have forward motion. . . then again, that is what the conveyour belt is doing.
They way I imagine it is this, if a car was placed on a ZERO resistant dyno (basically a big roller mounted to the ground) would the car ever go forward? If the car was then attached to wings, would the car take off?
Once again, I say no. . .
the wheels dont drive the plane. the thrust from the engine pushes the plane. the wheels with just spin at 2x the speed.
So wait >.>
let me get the wording correctly:
Scenario (which is how I interpret the situation) 1: For every forward motion that the plane travels the conveyour belt will counter it my moving in the opposite direction. I think the dyno rollers is a better visual description
Scenario (which is how every one who thinks the plane will fly is interpretting it) 2: The conveyour belt will only be able to match the speed of the wheels. Since the speed of the wheels will always be 1/2 the air speed of the engine (conveyour belt negates the other half) the plane will fly? I don’t like this interpretation 
Dyno roller idea FTW!!
The conveyor can go as fast as it wants. It just spins the wheels on the plane regardless. Doesn’t hold the plane back one bit because they are just free wheeling. The thrust will move the plane just like normal and it will take off.
:o ohhhhh >.<
EDIT: But wait… . that is under that assumption that the conveyour belt has no force at all. . . and in that case then the assumption that the conveyour belt will counter the forward motion would be dismissed. However, the problem states that the conveyour belt will counter any forward motion of the plane… If there is no forward motion, then how does a plane move forward to create lift?
its not neccessarily that i will counter it, it will just match it. plane moves forward at 100 mph, conveyor belt moves backward at 100mph, wheels spin at 200mph. check out hotrodkid’s diagram
EDIT 2:
If a plane was at a full throttle and the brakes were applied causing the plane to not move forward, how will the plane take off??
the plane would have to overcome the friction caused between the ground and the wheels, with enough force, it can take off
