They're doing it on Mythbusters.
This should be interesting...
I don't wish to make myself unpopular, but could someone explain, without getting bogged down in too much detail, what the big deal is with the aeroplane and the treadmill? And the ducks, while we're at it. I remember it being on C+ but I never read the thread.
I'll try to watch that one
I don't get it either. I also don't have sky to watch it.
It was me that started that horror thread on C+
Saw that episode a while back via newsgroups, it's an interesting one.
I'm on the edge of my seat here, what's it about? I don't get the planes and treadmills myth.
and? did it work?
Wasnt it something to do with Bonj thinking it could?
sorry if i was wrong
Edit, opps just read up above right this time.
I asked a friend today with a btec in avionics and he said no, uless you turned it around the other way and it was fast enough to get the plane moving. But it might be good to get it to stop in a short space.
i don't get discovery channel any more
RT - there was great debate on C+ about what a plane would do if the runway were a treadmill - would it take off or not? i cannot recall the conclusion - I think there wasn't one
As for the ducks, I assume it was the how many ducks riddle - variations on There are 2 ducks in front of 2 other ducks. There are 2 ducks behind 2 other ducks. There are 2 ducks beside 2 other ducks. How many ducks are there? I missed this though, so I may be talking through my neck
Shhhhh.....forget it...don't ask......quit while you're winning.
should i heavily edit my last post?
The conclusion was that quite a few people need to re-learn their Newtonian mechanics!
A plane is on a treadmill. It tries to take off. The treadmill matches the plane's speed in the opposite direction. Does the plane take off?
And the outcome-
Yes it does. (where's the smug smilie?)
It takes off because a plane's wheels are unpowered. The thrust comes from the prop/jet engine pushing against the air. So the treadmill cannot stop the plane moving forwards. And once it gets to normal take-off speed it takes off.
