thread can go bye bye now. plane took off, which seemed obvious to me. /shrug

"On a day with absolutely calm wind, a plane is standing on a runway that can move (some sort of band conveyor). The plane moves in one direction, while the conveyor moves in the opposite direction. The conveyor has a control system that tracks the plane speed and tunes the speed of the conveyor to be exactly the same (but in the opposite direction). Can the airplane ever take off?"

This is so easy to answer.

Yes, the plane would easily take off, the only difference being that the wheel speed would be twice what it is normally.

the plane can't take off. it's simple physics really.

Please, please, mod, any mod, ANY mod, end this thread. Everyone was intent on letting the show decide, but no one gave it up afterwards. No matter what, more and more people will see the thread, pick a side, and commence in the ongoing battle. It's futile. This like a legal P&N thread in OT.

Grammar fixed.

it is clear that jamie and adam do not know what they're doing. the show is for pure entertainment.


given the proper equipment, time, and money, the plane will not fly.

Hopefully you're joking.

Of course I'm not. They're not SCIENTISTS, they're fucking "special effects experts".

psh, calling them scientists is like calling britney spears talented.

If you read the thread, you would clearly see that I am amazing brilliant. Or trolling, your pick 😉

What does it matter what their title is?

Any scientist knows that it'll take off.

If you read the forum rules, the first 2 rules after #1 are: No trolling
Maybe you're just amazingly foolish?

Then you failed physics.

This has probably already been said, but a lot of confusion comes from how people misunderstand the myth. I explained it to a few friends at work (one a math major, the other a CE if that matters), and both got it initially wrong. Their impression was that the expectation was for the plane to simply take off almost like a harrier jet. When you describe it in terms of whether or not the plane will have any forward movement and thus ultimately achieve lift, the question becomes clearer.

it's certainly not my fault you can't understand simple physics.

Yet, the plane took off. Please take physics again and re-read the myth. You obviously don't understand propulsion, friction, gravity and lift.

Look, fisher, I *teach* physics and have been saying for 2 years that the plane would take off. It was done experimentally and the plane took off. What I am confused about is whether you're trolling in this thread, or if you really just have that poor of comprehension. But, before more of your posts persuade me to believe that you are, in fact, simply trolling, allow me to point out right now that the rule #1 in the guidelines for these forums is: "no trolling."

 

[SSSnail]

Alright, so we all (well, most of us) agree that the plane took off. Lock the thread and be done with before I toss some mothereffin snakes on that mothereffin plane, then the mothereffin plane wouldn't go nowhere.

Nevermind... I cannot help those in denial.

Sure the plane will take off......that's why the Navy has invested heavily in huge treadmills on their aircraft carriers to launch their jet fighters.....made the decks much shorter and safer than those antiquated steam catapults they used to use.

Wait.....they haven't and still insist upon using steam catapults for launching their jets.

Honestly, who the heck cares if it takes off or not......have yet to see any airport or aircraft carrier or anything/anywhere else trying this out to launch their planes. Instead, most of the research seems to be in the VTOL side of things. Seems a huge waste of research money to me if the treadmills work so well.

This debate reminds me of the "Driving with your windows down uses more gas than driving with your A/C on.....aerodynamic software proves it!" debate, which, of course, has constantly been discounted over and over. Sheesh.

......No one's saying that a treadmill running against the plane's direction of travel is going to improve its takeoff distance or time. 😕

And apparently, driving with your windows down does use more gas than the AC - above 50mph, but not below.

Drugs are bad mmkay?

This gibberish you have chosen to regurgitate isnt way out in left field... its not even in the stadium... your in the freaking Gate D parking lot, Row Z, space 284.

Me thinks you have no understanding of the problem itself.

a treadmill cannot stop an airplane from moving forwards.
