Will the plane take off?

It will take off because it's the engines that move it through the air, not the wheels.

The treadmill just spins the wheels faster, and the plane moves forward and takes off as normal, just with very fast spinning wheels.

yes it can. the engines create thrust against the atmosphere around them, NOT the ground. Therfor, it would still push the plane forward and take off.


its not a vtol :D it has to move on the ground to pick up speed, thus air can move past the wing creating "lift" if the plane aint moving then its not going anywhere.

ive seen all these before and there really not too hard. sort of makes sense.

Edit = lol at this thread, half are right half are women ;)

The wheels are free-wheeling, so a conveyer belt will just make the wheels spin in the opposite direction. The plane will move forward via the propulsion of the engines as if it was on a standard runway, and take off.

why would the wheels be going in the opposite direction? when a place takes off (going from L-R) the wheels are going clockwise, and if the plane is on a tredmill (going R-L) the wheels are still going clockwise, are they not?

Also if the plane is traveling at 10mph and the belt is also going 10mph is the plane moving?? i think not, if so when you go to the gym and have a long run on the running machine does it take you ages to get to the changing room :D NO
 
No, speed is required to create a pressure differential between the wings. All that would move are the plane's wheels - actually, just seen the above...

The wheels aren't being used to propel the engine so it would achieve the same speed regardless of the conveyor

you dont need the ground to move the plane. The wheels serve no other purpose than to keep the plane from scraping it's body all over the place when you try to move it. If it needed the ground to move, it wouldnt fly at all.

A plane gathers speed as a result of the thrust generating a forward force acting directly through the engine.

If it was the traction developed by wheels (like in a car) what would happen once it took off? ;)

This is correct, how can people not see this.
The wording of the question says that the conveyer belt matches and opposes the motion of the wheels, so the plane will always remain stationary as the belt accelerates at the same rate as the plane. No net forward motion = no lift on the wings = no take off.
As said - its down to the wording of the question.

And so it starts.

The wheels are moving in the opposite direction to the conveyer belt. Conveyer belt starts, wheels start spinning. Now start the engines. These force the plane forward by pushing against the air, therefore it moves forward.

If I'm running on the running machine, I'm simulating the wheels spinning against the conveyor belt. Add an external forward motion e.g. someone pushing me, and I will move forward.
