Plane on a treadmill poll...

[Kyle]

Thank goodness some of ya'll are coming around. I'm proud that you see the light (the correct one). Yes, the plane will take off and some of you have explained it rather well.

The "rolling a suitcase with wheels in the airport walkway" was rather brilliant.

I was wondering what you would say when you saw that this had started up again. But yeah it seems people are coming around, the percentages have changed a bit in the past few hours.

The smart people almost outnumber the dumb. Yea!!!!

I think the problem most people have (including me, initially) is that they imagine the plane would be able to take off from a very short treadmill, which isn't the case. The treadmill would need to be as long as a regular paved runway. But the thing I had the most trouble with is getting it through my head that the plane's engine drives it through the air, there is no power being delivered through the wheels. I'm such a car guy that it made that concept pretty tough to get ahold of at first.

I thought that I made that clear when I initially posted the question...

Suppose a plane is on a runway that acts as a conveyer belt. The conveyor belt is as long as a typical runway. The plane moves in one direction, while the conveyer moves in the opposite direction at the same speed as the plane. The wheels of the plane are free-rolling. Will the plane be able to take off?

[_Christian_]

it's rather astonishing to see how many people have trouble grasping such a simple concept

[BKgen®]

now that you guys explain it, i was overthinking, so basically, even if its on a treadmill, the plane requires the same amount of work to take off, regardless of the treadmill speed?

x2

[EclipsEvo8]

I fly a real Boeing 757/767, not microsoft, no the plane on the treadmill would not fly.

[BKgen®]

it doesn't matter.

the only way that plane's going anywhere is if Jack Bauer says it can.

[EclipsEvo8]

Jack Bauer is my hero, and Bruce Willis, lol. Looking forward to the next season of, "24", lol.

whats ur name?

cus i sure as hell wouldnt want a dumbass as my pilot when i fly somewhere.

[RISKYB]

good question, you almost got me

[Kelly]

I ALMOST got excited because I thought we were gonna let this thread die...

But alas...

I almost got excited because I hadnt seen you post in a while, so I was happy, but alas.

Have to ever flown a plane on a treadmill?

Lol. I dont want someone like him flying me if he doesnt understand this.

[yudalicious]

the wording of the question is ambiguous enough where it could be both. assuming the belt and wheels generate negligible friction, then yes it will take off.

How could it be both? You just explain why it would take off. Explain to me, given the question, how it wouldn't take off?

At first I imagined that with enough friction, it wouldnt. But after reading it seems like I'm wrong. It'd take off regardless, assuming we have amazing wheel bearings haha.

In the grand scheme of things, the friction created by the wheel bearings even in a real world scenario, would be minute in comparison. An airplane's/jet's engines could easily overcome that small amount of friction.

Bump

[IDCoconut]

The ***** will take off dammit.

[Jecht]

[IDCoconut]

some of you bitches can't grasp the concept of an external force.


put some damn rollerblades on and strap a jetpack on your back. turn the threadmill on to full speed while you go WOT on your jetpack. Where do you think you will end up? You'll be choking on the treadmills controls while the jetpack is feeling up your ass.

[Jecht]

Surprise!!1!

[joecoolfreak]

So will it take off?

[redrumracer]

yes/thread and lock please

[speedminded]

I so almost bumped this this week but got distracted while searching for it lolol!

Can't lock it because the poll has more idiots than not in it!

[joecoolfreak]

=-) I have already seen a no vote today

[EJ25RUN]

yes/thread and lock please

lol at your vote.

[redrumracer]

lol at your vote.

lololol shhhhhhhh

[tdurr]

lol this was dug up again? oh boy.. the question is flawed btw.

[speedminded]

What is flawed about the question?

"Suppose a plane is on a runway that acts as a conveyer belt. The conveyor belt is as long as a typical runway. The plane moves in one direction, while the conveyer moves in the opposite direction at the same speed as the plane. The wheels of the plane are free-rolling. Will the plane be able to take off?"

It looks perfectly clear to me?

[3.5altman]

I picked no but now that i think about it the answer is yes. An airplane would take off due to the thrust of the airplane engines acts on the air, not on the ground.

[BanginJimmy]

I actually read a couple pages of responses. I cant believe how dense some people are. They simply cannot get over the fact that the wheels on a plane are not powered and are free spinning.

[BB1_Luda]

LoL @ dumb people.


You know Mythbusters did this exact myth a month or 2 ago.
look that shit up.

The plane took off when it was on the treadmill.

lol, this and another thread was created well before the original airing of the show and I organized an IA meet for it lol!

That is 100% correct.

[BABY J]

I'm changing my answer... shit won't take off.

You mean a year and a half ago? It was shown on tv, if I recall correctly, Jan 30th, 2008.
