Stupid physics question

I can't believe I am trying to justify the correct answer all over again, 18 months later, one person at a time. This is why I was going to close the thread.

No i'm just winding you up :kissit:

 

[Will]

That actually makes me feel a lot better.

 

[Garaen]

Does that explain it better?

It does, thanks!

 

[old.user4556]

if the toilet roll was under instead of over, and they served "rounds" of toast, it wouldn't take off

 

[tris-]

it will take off.
relatively speaking there is zero friction between the wheels and the conveyor belt, so that isnt gonna stop it.

 

[TdC]

stop explaining it. anyone who doesn't get it after 27 pages of forum discussion deserves their blissful ignorance imo.

 

[Clown]

It won't take off.

This thread better still be open for when Myth Busters cover it next week!

Deebs was in my dream last night.

a lady coworker of mine was in mine. it was....disturbing

heres another conundrum i stole off another forum

Seeing as we're thinking about aeroplanes...

Say we have a type of plane that has a maximum take-off weight of 20,000 kilograms (i.e. it won't take off if it's any heavier).

We load the plane up and it weighs 19,995kg.

Then we add 10kg of live birds in a big cage, making the total weight 20,005kg (exceeding the maximum take-off weight).

If the birds were to start flying inside the cage, would the plane be able to take off?

 

[Chilly]

lol. Thats a non starter. The answer is no, unless you think birds have anti-gravity?

 

[Mabs]

no cos when they fly, they displace their own weight in downwards air as they flap their wings which pushes the cage and whatnot down

 

[Wij]

Stupid - how would they fly without air currents and thermals ?

Humingbirds maybe but 10kgs of them is like a million birds.

I refuse to answer as it's total shit !

 

[tris-]

how the fuck should i know? i just copy and pasted it from somewhere else FFS

 

[Tom]

I want to know if a helicopter on a turntable would fly.

 

[Chilly]

you havin a fucking laugh?

Fucking LOL!

 

[Will]

I've got an RC helicopter, but no turntable. I could attach it to my handblender...

 

[old.user4556]

What if the plane drank red bull?

 

[Krazeh]

Well have just watched the Mythbusters episode and, suprise suprise, the plane takes off as normal. Admittedly it wasn't exactly a plane on a conveyor belt but it was close enough and clearly shows planes will take off even if the stretch of ground they are sat on is moving backwards at the same rate as they need to be going forward to take off.

Am a little worried that the pilot they used didn't think the plane would take off tho. You'd hope that being a pilot would require you to have some idea of how planes work and what makes them move forward.
