Wow only 49% of IA is stupid lol...
was resurrection of this shit really necessary? at this point all it proves is that we have more dumbasses here on IA...
lol today is old thread day.
of course the plane will lift off LOL
FUCK I MEANT YES
yeah, after everybody got shafted by them hyping it up then not airing it on the date everything said they were!!Quote:

The answer is no. if the planes wheels are going 200mph and the treadmill is going 200mph in the other direction it will stay still, thus not being able to generate lift due to the lack of air flowing around the wings...
LULZ you are a retard.Quote:

The contact area where an airplane meets earth has nothing to do with the forward motion of a plane other than a VERY small amount of friction. Airplanes are propelled by air movement, not what is in contact with the ground.
The question you need to ask yourself is 'why would the wheels be spinning at 200mph?'Quote:

WTF 2006?
LOL!!!
I love the example of the water plane!!
I'll make it even easier for you.
Same plane and treadmill.
Take an ax, chop the wheels off, and put oil and butter on the plane's belly mixed with some secret KY lubricant that prevents friction heat (Lab tested in Amsterdam on Hookers), to make the belly extra slippery allowing it to just 'glide'.
Will the plane take off?
There's your answer right there.
I was saddened to see even some pilots arguing with such a basic concept. Airplanes are not powered by the wheels, no matter how fast the conveyor is spinning the airplane will still propel itself forward and lift off just like any runway or airstrip.Quote:

It won't take off, see. That the pilot is sitting on there pissed because he thought it would fly

btw, check what I voted 3 years ago....
:ninja:
I forgot about this thread. LOL @ everyone who said "NO." :taun:
x2. That's what got to me. Even the pilot on the Mythbusters episode was skeptical. It's crazy that people can know how to fly a plane, but don't fully understand how it works. :screwy:Quote:

yes its easy but not nearly as easy as a license to drive across land.
That's not the point i was making... But you are rightQuote:

Alright, new question for debate. How do planes generate lift?
Why is that difficult to believe? Because you know how they work and you are a pilot? That doesn't mean every pilot knows.Quote:

I have a full toolbox to sell off and I could use the cash if you need any work done.
What I find funny is Pilots saying "no". LOL.
Anyone can put the time and money to learn how to fly and actually fly...but not everyone can design a plane and know how it works.
49% of you need to shut the fuck up and go pick up a Dynamics book.
i dont, i dont have that kind of money to actually own a plane.Quote:

As the wind moves over the top and the bottom, the wind moving over the top goes faster than the wind moving over the bottom of the wing. That creates lift (if you really want to simplify it).
Given the education level of the majority of IA, the responses don't surprise me.Quote:
