Heh, I was origianally going to put in a caveat about the treadmill material. Doing it the way they were (dragging cloth across concrete), a longer (heavier) strip, being pulled faster might require a stronger material.

But that seemed like overkill.

lumberjim 01-31-2008 02:12 PM

i thought they would have done this with a remote control plane and a fabricated actual treadmill.

I don't think they appreciate the obstinance that the 'no take off faction' is capable of.

lumberjim 01-31-2008 02:13 PM

kitsune, you should start a poll in this thread. Make it public so that we can discriminate against those 'no fly' fuckers. k? thx...bai...

They did, earlier in the episode.

You see what you've done, Els? One harmless little white lie to stir some shit, and all of a sudden this thread is at the top again. I hope you're happy.

monster 04-07-2008 10:44 PM

This is what all y'all should be worying about now....

Elspode 04-07-2008 11:36 PM

No, no...its true. Its on their website.

Procedure/Experimental Design: Using Grant's model airplane & Jaime's treadmill, they do a small scale test to see if the concept is feasible. Setting the treadmill to 11.3 mph (the take off speed of the model plane), the model plane went forward, but could not take off due to the short length of the treadmill. Next, using butchered paper dragged behind Adam's scooter, they put the plane on the paper to see if it can take off. The airplane does take off before the paper runs out. As Adam & Jaime explain, unlike a car, where forward motion is derived from spinning wheels, forward motion on an airplane is derived independent of the wheels through the propeller. Thus, forward motion can be achieved on a conveyor belt.


Elspode 04-07-2008 11:54 PM

Damn it. I just watched the video. You didn't expect me to *read*, did you?

Why they gotta beat up a perfectly nice piece of paper? Methinks they mean butcher paper?

Is this like "battered fish"?

classicman 04-08-2008 08:10 AM

I still agree with you Els - even though the damn thing took off - It still shouldn't have.

Richie_uk 04-08-2008 09:56 AM

NO

It wont take off, the planes wings need air rushing through them to genarate lift. unless it can flap http://i285.photobucket.com/albums/l...7/gif/wing.gif :P

xoxoxoBruce 04-08-2008 10:49 AM

The air moving over the wings is created by the props pushing it or jets pushing the plane through it. The wheels only eliminate the friction between the plane and the ground, and are irrelevant.
Up it goes.

classicman 04-08-2008 11:02 PM

Holy crap - Here we go again! ::giggle:

Never mind will it take off?

Will It Put Out?

And would you risk a BJ? :eek:

:lol:

Ooh, a hovering BJ!

Well that's just great. We resolved "The 'Plane on a Treadmill' Question"; but, now we have to resolve "The 'Helicopter on an Escalator' Question". :headshake

zippyt 04-16-2008 10:41 PM

Many great minds of science have ruminated on this vital issue. They were less concerned with how close, though, than with how period, since landing upside down is no mean feat.

The leading theory for years was that the flies did a half barrel roll sideways a la the Blue Angels just before landing. This idea was shot down in 1958 when Natural History magazine published photos showing that in fact flies do a sort of backward somersault.

On approaching the ceiling, and while still flying right side up, flies extend their forelegs over their heads till they can grab a landing spot with the suction cups in their feet. Their momentum then enables them to swing their hind legs up, like a gymnast on a trapeze. Result: inverted fly, home and dry. So the answer to your query is, they get real close.

Dingleschmutz 04-16-2008 11:59 PM

Good lord, is this still going on? The plane takes off. I said so. /thread

What if...

lumberjim 05-16-2009 07:29 PM

you couldn't wait 10 days to post that?

also, it would go backwards

xoxoxoBruce 05-16-2009 08:57 PM

No, the wheel isn't driven by the belt, it's driven by the small roller/motor in front of the wheel.

lumberjim 05-16-2009 09:07 PM

oh..i didnt notice that.

so, that wheel reverses the direction.....

xoxoxoBruce 05-16-2009 10:25 PM

The caption I saw with the picture said the wheel was driven separately from the belt. It didn't explain if it was a separate motor or some kind of linkages.

shit. now what.

What about this Shrimp on a treadmill?

I forget where it came from and what the researchers were attempting to discern.


xoxoxoBruce 11-03-2012 05:42 PM

Or where they found such a stupid shrimp. :unsure:

plthijinx 11-24-2012 02:26 PM

i'm too hungover for this.

i'll think about it tomorrow when i go fly with Bobby.

Will you be taking off from a treadmill?

ZenGum 12-17-2012 07:23 PM

Okay, in regards to the eternal question of "can it take off from a treadmilll?" the tally so far is planes, yes, pigeons and shrimp, no.

What about coked-up reindeer?

Quote:

To compare nasal blood flow across species, the research team recruited five human test subjects from the Academic Medical Center at the University of Amsterdam, where some of the authors are based, and shoved a video microscope up their noses to chart blood flow. Furthermore, the researchers tested vascular reactivity (i.e. how much the blood vessels can change) by "local application" of 100 mg of cocaine, a common vasoconstrictor used in ear, nose, and throat research, to the interior of one of the subject's noses.


The team then anesthetized a pair of adult reindeer and did a similar microscope survey of blood vessels, then put the reindeer on treadmills to heat them up, and recorded where their heat output was highest with a thermal imager:

There is no record of the reindeer achieving lift-off.

I guess they need more cocaine.
