Actually, we will. Read the thread. There's nothing "magical" about this scenario that can't be predicted. The conveyor and wheels do nothing to hinder the planes takeoff. Think about it.


I'm currently making a flash movie that shows the process. (A narrated one!)

You can predict all you like, but you'll never...REALLY know...you know?

You know.

Oh, but my flash movie was made using the latest of physics simulation thrust friction flux technology. It's even realler than real life. So you'd better believe it.

WTF!?! RL HAX!!
 
One thing i don't get from vegata's flash movie was how the fact that the jets were powering the plane made it move forward... In the original post, it's setup so that the conveyer speeds up with the plane, so shouldn't the plane still be in the same spot?

Nope. The only thing the conveyor belt affects is the speed at which the wheels rotate, and since the aircraft doesn't rely on it's wheels for propulsion, the conveyor belt doesn't affect the propulsion of the aircraft.

Actually, it is pretty generic. Although, almost everyone I've talked to online with voice has a much deeper voice than mine, despite the age.

And Sepith, I'm sorry my Flash didn't get the point across, the key point is free moving wheels. The runway could be moving as fast as it wants (assuming the wheels don't combust from the sheer speed or anything like that, I'm talking in a theoretical world) but the plane is still only affected by the jets/propellers pushing it.

not that much deeper, I think. I dunno, maybe your lack of "nubcakes" is throwing me off :O

Nubcakes? lol, what do you mean? When I'm actually talking about interesting things I can get pretty crazy and fun with my voice. All the people I talk to have the same boring lowish voice and never seem to have any... feeling.

Oh, I see. It'd be like me running on a conveyor belt, and if I spit a piece of gum at vegeta, who is standing in front of me, the gum wouldn't just drop at my feet, since the propulsion of the gum is completely independent of that of my body.

That's a bad analogy, but I understand now.

like, usually, there's um... I always end up in servers where's it's only the assholes using the mics, the ones that are always yelling Hax! and Noob! and...stuff.

anyway, yeah, I bet my voice is pretty generic too... although I hear it gets higher when I'm excited :P

Right, I've seen this on 3 different forums now, apologies if its a repost but here goes.

I want to see how many people correctly answer the following question before the thread descends into a flame pit of "YOU DESERVE TO DIE" and "YOUR A NOOB SHUT UP STFU" :D



And I already know the answer.

Lighting the blue touch paper.......of a bomb/explosive.

I.e he's going to make a thread that is going to explode into argument, therefore lighting the touch paper (fuse)

.....I presume.
 
Anyway, all I'm really trying to say is that all science is flawed at a basic level.

/me runs
 
...wow this went on for 10 pages?

Guys this isn't rocket science...or is it?

He said the plane moves in one direction, not the 'right' direction needed for take off, just a direction--so i say the plane moves backwards by being pushed by one of those little cars; so no, the plane never takes off.

He doesn't say the plane ever tries to take off...planes can move without taking off; so no, the plane never takes off since it never tried too. That isn't to say the plane can't take off, just that it wont. Which is what he asked.
 
Now both answers are occurring to me, for different (indeed, opposite) reasons.

I don't know whether the conveyor belt would serve to pull the plane backward.

I accidentally placed a cucumber sideways on a supermarket cashier's conveyor belt once; that belt pulled the cucumber back, but the cucumber rolled forward as well, so its position was entirely stationary. A cucumber is not a plane, but I was under the impression that a conveyor belt operating on a wheel would pull backward on both the wheel and whatever it's attached to...
 
Ah, So the wheels are NOT irrelevent. They are the most important fact in the question. So basically the wheels' free motion negate the conveyor, and the plane accellerates as if it were just starting its engines in air?

Wheeee! I think I finally understood it somewhere on page 8 lol.
 
I'm sorry to say it but the plain wouldn't take off, your all ignoring the effects of gravity and friction.

the wheels DOES matter! as they create friction...the conveyer belt is moving the opposite direction of the plane at the exact speed of countering any movement from the plane. the plane is moving nowhere and will not move untill it manages to counter the friction created by the wheels, and the only way to do this is getting off the ground. seeing as the the plane isn't moving in relation to the air around it, there will be not be sufficient air passing by the wings to create the lift necesary to counter the friction of the wheels.

so the plane wouldn't take off...unless:

a) it has a downward pointed propulsion system that is able to lift off on it's own. like a harrier jet or rocket.(note normal jets are unable to lift of by the use of their engines alone, they can propell themselves forward but not fast enough to lift off without the aid of passing air, if they're not moving there's not enough passing air to lift them)

b) the plane is in a wind tunnel powerfull enough to get the plane off the ground on it's own.
 
So from what you're saying is something like "since the fact that the plane is moving forward, the conveyor belt is speeding up to compensate, and when the plane continues to move forward, the conveyor belt speeds up so fast that it generates SO much friction as to slow the plane back down".

I stay in the "it will still take off" corner because I posit that should the conveyor belt reach such a speed, it would blow enough air onto the aircraft to generate the necessary lift, because of the absolutely insane speed it would have to go to generate enough force through wheel friction.

Yes, there is gravity, there is always gravity, it's always pushing the plane toward the ground...why the heck do you think it has engines?
The engines > gravity, counteracting everything else and lifting the plane off the ground.

That wasn't the point. Gravity + wheels = rolling friction.

the question tells that the conveyer belt has a control module for matching its speed against that of the airplane. so the plane won't move.

it will blow air but not enought to lift.

But the plane isn't powered by the wheels like a car. If the conveyor belt moves faster, the wheels just skateboard faster with little change to the friction.

Dude, you are saying the exact same thing 10000 other people have said, and we proved them all wrong. Watch my flash video if you don't want to read.

The runway is only affecting the wheels of the plane, the jets or propellers are pushing the plane forward no matter what, and the conveyor belt does nothing to stop it, except spin those wheels backwards.

:x I would have though everyone would understand by now.

Tell me Prince, why isn't the plane moving when it has jet engines pushing it forward? Because the runway is moving backwards you say? Well guess what, that's why we have wheels to take in all the spinning, leaving the plane unaffected and free to move forward.

I swear, I'm about to make another Flash movie where I go into every gruesome detail while screaming at the top of my lungs, and slinging numerous insults all along the way.

How does the plane stay in the air without a magical conveyor belt then?

no the friction might remain the same(key being that it's the same as when it prevented the plane from moving).

but plane still won't lift.

because there's no change in the gravity of the plane or lift it gains.

1) engine thrust

2) air passing the wings

3) no friction from the ground.
