That's pointless, because then, if the plane is going 25 mph forward, relative to the ground, then it is going 25 mph relative to the ground and it takes off. So why even pose the question of the myth.

Basically the myth should be cut off at "the plane is moving forward at takeoff speed, relative to the ground" and that would be end of story. You can say anything after that but it would not negate that you stated that the plane is going at takeoff speed relative to the ground.


The purpose of the question is to test a person's reasoning skills. Not everyone would immediately understand that the plane will take off. The freaking pilot on the mythbusters episode didn't even understand the situation.

Rex, your thread made me sad. I have like one strand of hope left. I'm one Bush speach away from offing myself.

OneManArmy is correct. It's like a logic puzzle.

Then it should be a brain teaser and there would be no reason, what so ever to even try it.


I was so friggin pissed off after spending a whole hour watching mythbusters thinking they would actually come up with a way to make it stationary. When they started moving both at the same time it was such a let down. I knew before that wasted hour that the plane would take off if that was the case.

To me that would be the challenge. Make it stationary, for however short a period of time. Hell even I figured out how to do it.

As OneManArmy said, the whole point of the puzzle is that it is not intuitive that the plane will take off. People think that the conveyor belt will cause the plane to stay in place, which is never the case. Once you think through it and apply physics, you realize that the plane will take off no matter what the speed of the conveyor, as the forward velocity of the plane and the backward velocity of the conveyor are almost entirely (expect for a small amount of friction) mutually exclusive.

I already explained earlier how it could be accomplished in practice for a moment.


Sorry, that won't cut it. The plane may be stationary for a moment, (btw, we call this a trivial solution) but it is still accelerating forward. That single solitary moment of zero velocity will not prevent the airplane from moving forward and taking off.

But if it makes you feel better, then yes, at that single, brief point in time when the airspeed is zero, the plane will not take off.

And that is the way the myth is worded. Because only at that moment is the plane and belt direction moving away from each other at the same speed.

No, it's not.

If a conveyor belt is set to the same speed as required for a plane to takeoff, in the opposite direction, will the plane take off?

I find it highly amusing that gambo is calling everyone stupid but fails to understand how people are changing the basic conditions of the experiment in order to attempt to prevent the plane from taking off.

That's what I call ownage.

oh i see it dont worry

but those conditions are not contained within the original myth

The fact that those conditions are not contained in the original idea is irrelevant. You are calling people stupid for attempting to come up with new and innovative (relatively) to keep the plane on the ground.

Let me guess, you're an engineer who is incapable of thinking beyond what you learned in school?

So, i take it no one watched the youtube link?

Dood did a free body diagram, even though common sense told me it would take off before, its pretty nice to see it solved mathematically and physically.

neurotic i appreciate the lesson

however im quite the creative person

BUT

i fail to see how there is any discussion in wheels locked, or engine turned off modifications to the myth

No, I was referring to the idea that assuming an indestructible plane and conveyor belt and a conveyor belt capable of infinite speeds, could you run the conveyor belt fast enough to prevent the plane from taking off? (in essence, using just the friction generated from the plane wheels moving at super speeds).

That's called over thinking the myth and shows a lack of common sense from Ph.D. morons like you.

but then we could also assume perfectly frictionless wheels and then the conveyor is moot again

Many people mocked Einstein for overthinking light, gravity and time when he developed his theories of relativity.

Don't blame me or say that I lack common sense because YOU are incapable or unwilling to think beyond your own pathetic little world.

Also, what does the original myth have to do with common sense? We don't have any conveyors that big and are unlikely to do so in the near future.

Anyone still arguing that the plane wouldn't take off even if dragged backwards a little at the start is a goddanged dumbfook. Anyone arguing that matching the speed of the wheels would keep the plane from moving forward is a goddanged dumbfook^2. Please if you are in any engineering field or a physicist please tear up your degree and apply for a job at McDonalds. Every concept necessary was demonstrated by the Mythbusters and is logically obvious even without the video results.
