b) there's no realistic way a treadmill/conveyor belt could ever stop a powered plane moving forward.

Stick it in a Vacuum chamber

But then it wouldn't really be the treadmill/conveyor belt stopping the plane moving, it'd be the lack of air. All you've ended up doing is changing the plane from a powered one to an essentially unpowered one.

Yes to the first half but no to this bit - its still powered but it cant create the uplift.

Another idea is to connect the treadmill to a big fan - if you can generate enough contrary windspeed it cant take off.

 

[Krazeh]

Suppose that depends how you define powered. It'd seem to me that any current plane requires air in order to produce thrust, without it it's not producing any thrust so is it powered? Furthermore a jet engine requires air in order to even operate so without air it wouldn't be able to start so a jet aircraft would definitely not be powered in a vacuum.

Another idea is to connect the treadmill to a big fan - if you can generate enough contrary windspeed it cant take off.

Again that's not the treadmill is it? It'd be the fan creating a contrary airflow and leading to zero airflow over the wings. Mind you it'd have to be one hell of a fan and even then i'm not sure it'd even work.

The problem here is that you are all so busy slapping each other on the back telling yourselves how smart you are that you can't see the very simple foundation of the problem.

Under the given rules of the experiment the airplane does not fly.

The most basic principals of Newton's law are at work here: Objects (mass) at rest stay at rest, objects (mass) in motion stay in motion. It requires ENERGY to change each of those from one to the other. It is possible (and required by the rules of the experiment) for the energy of the conveyor belt exerting itself against the wheel of the plane (in the form of rotational inertia) to sufficiently cancel out the forward thrust of the propeller.

Under the given rules of the experiment the airplane does not fly.

 

[MYstIC G]

He won't supply any proof because:

a) he doesn't understand the thought experiment properly in the first place, and
b) there's no realistic way a treadmill/conveyor belt could ever stop a powered plane moving forward.

c) neither he nor his friends can even answer a question about their own sexuality

Could you possibly fit more bullshit into one post? The plane and the ground are essentially unconnected, the whole point of the wheels is to produce as low a level of friction as possible, they have no involvement in the plane's locomotion. Once the engines have overcome the negligible amount of friction in the wheel bearings the wheels can be taken out of the equation. There is simply no way (without descending into wholly unrealistic situations) that the action of a treadmill on the wheels of a plane can prevent that plane moving forward or taking off. The plane is pushing against the air, what the ground is getting upto is of no consequence.

 

[Wazzerphuk]

I can't believe you chumps brought up the treadmill plane thing again. Oldest and most boring argument on the internet.

So, for all you fatties - how do you actually get fat? I'm trying to put on weight and just simply can't manage it at all, it's fucking ridiculous. Eating more food, eating more fat and since yesterday I've lost half a kilo or thereabouts. Probably just typical water loss after gym session, but still trying to put on weight I've managed probably 2 kilos in total.

 

[Scouse]

It has been well documented that that myth busters episode did not conduct the experiment properly. It is, in fact, impossible to replicate the experiment in the real world. It is merely a mental exercise.

Yes. And the "mental" exercise using laws of physics told to 12 year olds in this country show that the plane will take off. It's simple.

It's fuck all to do with wheels. But then, of course you're going to ignore the proof, mathematical, physical or otherwise.

Troll.

If your only trying to prevent it flying you dont need to get it to zero just keep it below the airspeed required for takeoff.

 

[Krazeh]

Fair point, I still say it'd require one hell of a fan in order to create the required wind speed and maintain it as the plane moves away.

Have you guys ever had a thread over 100 pages before? I'd do a search, but being a fat and lazy Yank its too much work.

So... On your side of the pond there is no energy exerted in the acceleration of a wheel? I can't help you.

This is a prime example as to why your lot haven't come up with anything of use in the last hundred years or so.

 

[nath]

The fact of the matter is that if the conveyor belt is reversing as fast as the plane is moving forward, the wheels will simply spin twice as fast. Obviously if a plane is stationary relative to the ground/air it won't take off hence chocks, the point is a conveyor belt going backwards won't stop a plane moving forwards. It's a simple question blown way out of proportion by masses of people getting confused. Much like yourself, SoS.

No energy from the plane's engines, no. Any energy the wheel obtains comes from it's interaction with the ground, that however isn't transferred to the plane due to the bearings in the wheel hub essentially disconnecting the wheel from the plane. I'm not sure what's so difficult to understand about the concept but what the wheels and the ground get upto have no impact on the plane's ability to move forward. The plane moves via pushing against the air, the ground has nothing to do with it.

Talk to me bitches!

Or venture into OT, quite a few gym freaks over there

5 to 6 meals a day minimum. Smaller meals, but every 2 to 3 hours, include protein in each, use a good quality (though not expensive) whey protein. You need to be eating a minimum of 3000 calories every day + 1.5 to 2x your body weight in KG of grams of protein. I've seen you are a skinny fucker like me, so this really is the only way. You need to eat like this every day, and you need to really push the weights.

If you aren't prepared to do this, then you'll become toned, but the mass gain won't happen.

No. On our side of the pond we understand that un-powered wheels have nothing at all to do with the acceleration of a plane.

The moment of force is at the engine (a propellor in this case, a jet in the case of other planes). Wheels simply don't come into this at all.


This is a prime example as to why Americans have the reputation of being some of the most under-educated, ignorant, full on retarded people on the planet

 

[Ch3tan]

Okay, so we've proved that they have no idea about the plane and the conveyor belt. Now for the important issue; toilet roll, over or under?

Oh please God, can we stop? Its 2008 all over again. And it was a shite conversation then.

Reading comprehension is not your strong point, is it? The conveyor belt is matching the WHEEL'S speed. Big difference.

 

[Krazeh]

Aside from the fact that isn't what the actual thought experiment says, it'd still make no difference as to whether or not the plane moved.

 

[Tom]

Sigh. So what if it is? The wheel has a bearing which allows free movement, and the aircraft is connected to the wheel through that bearing.

You're either incredibly stupid, or trolling. I'm voting for the latter (you should be flattered).

 

[nath]

*You* said matching the wheels speed, that's not actually the question though.

Additionally, it *can't* match the wheels speed as the conveyor will endlessly be playing catchup to the wheels speed until the plane takes off or the wheels snap off.

Ch3t, Wazz, I have lots of lard I am willing to donate you. Then you'll have some of me inside you ...forever!

 

[Son of Sluggish]

Think about this. An airplanes wheels continue to spin after it has taken off. What does that tell us?

(dragging by the nose)

Did the wheels spinning happen without consequence to the forward motion of the plane?

 

[TdC]

oh god he's not getting it OH GOD KILL ME NOWWWWWW!!!!






ps dinner time see you lot laters

 

[nath]

All of the information to realise you're wrong is in this thread, same deal with the atheism thing, same deal with homosexuality. There's absolutely no point discussing it further, perhaps you'll work it out, perhaps not. I'll try not to lose too much sleep over the outcome .

 

[Krazeh]

(dragging by the nose)

No, the wheels spinning happened because they moved along the ground, it had nothing to do with the plane's engines causing them to spin.
