Will the plane take off? v. Mythbusters!!! (VIDEO on Page 38)

[d993s]

Try the example with the match-box car that I said.

Trust me, the plane will move forward, accelerate, and eventually take off.

Take off from the treadmill? No.
Once it clears the treadmill it needs sufficient lift under its wings to leave the ground, unless its power output is increased at least 3x AND it is pointed up, vertically, off the treadmill.
Is the treadmill flat, or at a 45 degree angle?

reposter

[turbosx©]

i say its gonna take off.

[BKgen®]

i say its gonna take off.

God that sig is disgusting

The plane won't lift off unless it physically moves forward. Remember kiddies lift is crated by accelerating air over one side of the wing. If the atmosphere doesn't move across the surface area of the wings the plane will not lift off.

They also fail to mention if they are going to allow the plane to make progress down the tread mill all I see is talk of a matched speed. Secondly, is the plane being supported at the speed or are the engines of the plane matching the speed? Third, what is the treadmill's speed? If its 5mph big deal but if its lets say 200mph and the planes engines are doing the work to keep up then there is the problem of reserve power to out match the treadmill IF its allowed to make forward progress.

Lets say the treadmill doesnt end, then yes the plane will take off but it will requier more energy. It has to make up for the friction of the rotating wheels.

Long story short there isnt enough information in the question to answer it correctly.

So on that note i win the bets gimmie all your money lol.

[Jimmy B]

ohh ya i forgot i can't ask questions without ur approval my bad

i was just stating a fact that it was not said... dont get your panties in a wad

and yes, you have my aprovial now..

[umairejaz]

The plan will take off. My bet: $50

[coolcat]

IT WILL MOVE FORWARD!!!!!!

I cannot wait for this show to air.

If the treadmill is the length of whatever length a normal runway needs to be, it will gain enough speed and finally take off.

You said that it WILL clear the treadmill, so you admit that it will move forward. Well, given a long enough treadmill (typical runway), it will gain speed and lift.

[Ruiner]

IT WILL MOVE FORWARD!!!!!!

I can't, either.

[Ruiner]

d993s, vote up!

[redrumracer]

after thinking about this for a long time i say it will. i used to say that it wont, but if you think about how an airplane works then you will realize that it will take of. a plane doesnt depend on ground speed but rather its speed through the air.

[ep9716]

No.....I Don't Think The Plane Will Have Any Lift...That Sh1t Could Go 200 Mph...With No Lift Theres No Flying..

But Idk....Lets Wait And See..

[umairejaz]

No one taking my bet? I'm willing to raise it.

[crf150]

im a student pilot, i already soloed in a cherokee 180, but im still confused about the experiment. will the plain have its own power?

you sure ur a student pilot? LMFAO

[Deke]

damn, not this again. Can't wait for the show.

[crf150]

yeeeeaaaa i fly 8891J out of berry hill. and sometimes out of tara.

[Benefit]

fukk every1, the plane will crash into a building

[On_Her_Face]

yeeeeaaaa i fly 8891J out of berry hill. and sometimes out of tara.

so you fly plaines?

[crf150]

would u like to see a copy off license?

[Echonova]

I have not read one post in this thread, but are we really gonna start this debate again?????? FTL. Make it past 7th grade and you have your answer.

[Benefit]

would u like to see a copy off license?

im guessing english isnt your 1st language

[Echonova]

would u like to see a copy off license?

Yes.

[On_Her_Face]

would u like to see a copy off license?

yes i would like to see you're PLAIN liscense

[Echonova]

..

[crf150]

here it is

[On_Her_Face]

lol echo with his ****ing pictures

[On_Her_Face]

here it is

ohh so you fly planes?


i thought you said you flew plaines

[crf150]

pylots dont have tu spel gud. u should see the pilots delta has now. there training time is down to like a 1/4 of what it used to be.

[Echonova]

here it is

I'm sorry; I meant your current one, that expired in '06. Also there was no name to identify as it as being yours. Clarification is needed.

[crf150]

thats because i stopped training. im gonna start from the beginning again at mtsu. all i need to renew is a physical i think. so go to my myspace for my name im not going post up my drivers license.

You don't have to post your drivers license. Your Social Security # or a major credit card is all I need for verification.

[crf150]

maybe if i had a credit card....i gotta go to bed im goin to school in the mornin...its been a blast.

Plane doesnt get off the ground(lift, not bouncing or falling) under a conveyor. My bet: Pink slips to this

[Fast Shadow]

We've known the answer to this for years. It's Newtonian ****ing physics. If you answer no you should kill yourself now.

[Magnus213]

If the plane is accelerating relative to stationary ground (not the treadmill- stationary ground) and the treadmill is of infinite length, the plane will take off. If the plane is not moving relative to the ground, it's not going anywhere.

Air moving around (specifically over and under) the wings creates lift; if the plane it not moving relative to the ground, that also means that it's not moving relative to the air around it (assuming zero wind). No air flow over the wing = no lift = you're not going anywhere.

Yup. I've always said no to this but I've also interpreted it as the conveyor belt is freewheeling and unpowered so that it matches whatever forward speed the plane has with an equal backwards speed. Overall velocity is zero since no distance is covered, with no headwind its airspeed is zero and no lift will be generated.

If the conveyor belt is at a constant speed then yes the plane should be able to accelerate and take off in time. The problem is vague and left open to lots of interpretation.

[IDCoconut]

I'm not reading through the entire thread.....

But the plane, in theory, WILL MOVE FORWARD, it will have to work a little harder because the wheels, even free rolling, has a lot of friction within itself (bearings, etc.). The reason the plane will move forwards is because the plane's propulsion is not via the wheels, it is via the jets which are mounted on the wings and have no relation to how fast or slow the wheels are spinning. The wheels are merely there to hold the plane up, not move it forward.

This is my take on it. If you're takeoff throttle position is @ wide open throttle and it takes you 45seconds to reach takeoff speed, it may take a little longer to reach takeoff speed with a conveyor belt going in reverse for the simple fact that the wheels will be creating friction on its bearings that the jets have to overcome.

That's my take. So I vote YES that it will take off.

[RandomGuy]

20 bux paypal on it'll lift off... anyone wanna take me up on that?
