I haven't lost the argument, just answer the question above, will the plane leave the ground or not.
It doesn't matter if it's nonsense, irrelevant or just plain stupid. yes or no.
conveyor belt and plane answered at last ??

I know its aimed at Joe but my answer.........if that above is the final version of the question then NO it will not take off....it can't.

That was the original post goes back years.
Blame Big_All
Don't worry Joe, they couldn't even build a conveyor belt/runway to test the theory, and if they could it would cost millions.

So doitall.....
If we were to attach a cable to the nose of the aircraft and apply a force of 120,000lb (approx 53 tons )
we would not be able to move the aircraft forward, because the free wheeling wheels would brake it...
By the way, attaching this cable with 53 tons of force, has EXACTLY the same effect as firing up the jet engines.

Why would you want to do that
Outside of the parameters of the question the plane can take off as normal.
Inside the parameters of the question the plane can take off as normal.
At last............

What does that mean. You haven't read or understood the question.
The only relevant information is in the question, and there's only one correct answer. No the plane cannot take off.
We can all change words to further the argument.

Yes or no.
Cough.
Either it's a word riddle, and the plane is moving forward (it can't be described as moving in a direction and not be moving = moving forward = takeoff), or it's a physics thought experiment, and anyone should be able to figure out almost frictionless ball bearing free spinning wheels, will not provide anywhere near enough traction to stop the engine pulling it forward, any-more than applying the breaks mid-air will stop the plane.

always my fault doitall
lol the simple fact roller bearing are very efficient so at slow speeds the friction is virtually nil
you need to work out how much energy is needed to accelerates a plane to say 20 miles an hour you then need to work out how much energy can be transmitted via the wheels before they spin and the plane stays still then run the conveyor a bit slower than that
i am off the opinion the friction is so minimal 15 to 20mph will be the maximum you will reach before wind drag exceeds the available friction from the bearing and tire deflection so the whole idea is a non starter
The wheels of a aircraft have NO drive.
The drive of a aircraft is supplied by the thrust of the engines.
Therefore- it is as if the aircraft wheels are on a ice field with no grip.
YES the aircraft WILL take off. Unless of course a drunken pilot puts his foot on the brakes.
Similar/ish to a rolling road on MOT test.
The wheels simply hold up the fuselage off the ground.

Exactly.
Ahh back to my car tuning days, witnessed many a time a car lift up out of the rollers on a rolling road, this is a very good example of the engine overcoming the backward rolling motion of the rollers......OR CONVEYOR BELT
and moving forward.If the plane throttles up then it'll overcome the backward motion of the conveyor and it'll move forward, but the question stated the wheel speed remained equalised with the conveyor, if the plane moved forward the wheels would be travelling forward faster than the conveyor is moving backwards...........this isn't what the question asked
