What the hell!?!?! Quit overanalyzing this and let the thread die. Crap Brett.....

Sam Drake? He's the man. Sc.D '78 MIT.cruiseroutfit said:PS, I just ran this past a room full of ME students, Prof. Drake is drawing a free-body diagram as I type... He's convinced it flies!
Cody said:lol, ok, I'll stop. I need to stop wasting time being a jerk.

He's by far my favorite instructor at the U. I'm majoring in EE but I enjoy his classes so much I might continue to take ME courses and just double maj.cruiseroutfit said:Yes sir, Dr. Drake is our Mini-Baja instructor and I have had a couple other classes from him. Awesome instructor. The guy is a brain, 4 degrees from MIT!

OCNORB said:Either that or we're smarter than you- That conveyor belt would have to break the laws of physics, so I say that while theoretically it would fly- in the real world there is no way. -Prove me wrong smart guy!
pilots lounge said:The "It won't fly, Rocky" group said that the conveyor would hold back the airplane. They asked us to imagine a person running on a treadmill. As he or she sped up, the treadmill would be programmed to speed up, just as the conveyor in the problem, and the person would remain over the same locus on the earth, while running as fast as possible.
The argument was that if the airplane started to move forward, the conveyor program was set up to move the conveyor at exactly that speed, in the opposite direction, thus, the airplane would never move relative to the ground, and, because the air was calm, it could never get any wind over its wings. One of the analogies presented was the person rowing at three mph upstream in a river on a calm day. However, the current was flowing downstream at three mph, so the resultant speed with reference to the stream bank and air was zero, and thus there was no wind on the rowboat.
I watched and listened to the disagreement for a while and was fascinated to see that the argument seemed to split between those who had some engineering or math background, all of whom said the airplane would takeoff and fly without any problem; and those with some other background, who visualized the airplane as having to push against the conveyor in order to gain speed. Because the conveyor equaled the airplane's push against the conveyor, the airplane stayed in one place over the ground and in the calm air could not get any airspeed and fly.
It was an interesting argument, but as things progressed, more rational heads prevailed, pointing out that the airplanes do not apply their thrust via their wheels, so the conveyor belt is irrelevant to whether the airplane will takeoff. One guy even got one of those rubber band powered wood and plastic airplane that sell for about a buck, put it on the treadmill someone foolishly donated to the Lounge years ago, thinking that pilots might actually exercise. He wound up the rubber band, set the treadmill to be level, and at its highest speed. Then he simultaneously set the airplane on the treadmill and let the prop start to turn. It took off without moving the slightest bit backwards.

Fester said:You are both wrong . Chin is the man .......if he is still there. "Wapo Wato Pwesshho". Is Strojer (sp) still there too? I might be too old to play .
cruiseroutfit said:Kuan Chen the Thermo II & Heat Transfer teacher?
There is a James Stroizer? Not sure if that is the same, I have never had a class with him.
Fester said:Yep, oops, Chen not Chin.
Tacoma said:uhm I've actually jumped onto a treadmill on a skateboard and the only reason I rolled off the back was because that was downhill. It's kind of like those artificial waves.
heheheh
what kind of coconut was that again??
