Plane

[Deleted member 35927]

So the travellator moves alongside you at the speed you are walking, does it?
As well as the trolley you have hold of.?
If that’s the scenario, then replacing your pushing power of say 2 mph with the thrust of the planes jets to say 180 mph will cause the plane to lift off ( with some flap)
But where the hell in the image is there any suggestion that the treadmill(travellator, whatever) that the plane is shown to be on, is meant to be moving (at 180mph).? What indication is there that the treadmill, together with what it’s built on, is capable of moving forward, let alone at 180mph and for a distance of a mile or thereabouts.
The image to me (and others, I think) indicates that it is fixed to the ground.
And if it is, then no air is passing over the wings to give lift.
Nothing is moving but the wheels and the treadmill they are on. In opposite directions, and so cancelling each other.

In his example the travelator is moving in the opposite direction to what he traveling.

I really want to see someone try it

It's obviously yes, but I'm surprised how many try and argue otherwise.

Congratulations for taking Swango on a long journey where he is so thoroughly confused he doesn't know what day it is.

Swango took the time to read and digest then come to a conclusion.
Others jumped straight in , got it wrong but doubled down on that

How is this thread still going?

I see reading through that a few goal posts have been moved to make it “work” the treadmill is now two miles long and it doesn’t go fast enough to negate the forward movement of the wheels.

It's still going because you just kept it going.......
I think your getting confused , it will always work, no need to make anything fit. The conveyor would have to be sufficiently long enough for a standard 747 take off how ever long that is or whichever plane you choose.
It's pretty straightforward science, no magic, no tricks and no moving of goalposts.


Edit, please don't tell me youre taking the image literally

 

[Swinglowandslow]

If you are taking the image literally, then as soon as thrust is given by the engines then the plane will just fall off the front of the treadmill.

So, you have to really assume the treadmill is the entire runway, or just respond the plane crashes to ground in front of treadmill

Jesus H ….!!!
So what is all this about then, a treadmill the length of a runway?..

What a load of…daft hypotheticals

No it's not
To tricky for some to grasp I guess .

Haha. Were you more comfortable with an aeroplane on an aeroplane sized treadmill, but it got daft whe the treadmill was the size of a runway?

Surely this is an early contender for the worst thread of the year award?

Surely that would go to a thread with zero replies?

It’s only a thread if it gets replies.

It’s a question that’s been posed on countless forums for donkey’s years, and always sees the same arguments and counter-arguments.

Well, H is the one who gave us the image. Was he too lazy to describe it accurately in words.

And I still think that parameters like friction etc aren’t being taken into account.

But as Ken says, maybe it’s time for H to go out and try the real thing on the lake or river, and take some proper bait with him

Absolutely pointless then if it has already been flogged to death countless times.

You do realise you've been hooked?

There are hundreds of threads I've zero interest in. You'll know the ones, they are the ones you will have seen no comments from me.

This is definitely the thread in which many have left logic at the door

Ha! I’m about to slip my hook. Ta ta.
