10/06/2006 Entry: "lots of stuff" Quick update first: I did my first oregon juggling show last weekend. Another fellow and I are starting a performance group. I unicycled down a huge trail with watefalls this weekend as well. Pictures to come eventually. Now, the meat: For the Linquists: *(Technically they know what causes blocks, but not what causes the repetition that eventually causes the blocks.) For you Physicists (and anyone else with have a brain: I present to you a "brain teaser" that has me questioning the quality of education received by people at ISU. Several Aero-E's, Comp-E's, and general whatever E's got this shit wrong on Strangetalk. I don't understand how an engineer could get this wrong. I can, maybe, understand how an normal person would, but after it's explained to them they better slap their head and go "duh!" However, even with that happening people still argued the wrong answer. *sigh* I'll post the thread after you all try to answer the question. Don't worry, if you get it wrong I won't think you are stupid. It's ok to get it wrong... A long as you accept the correct answer that I give you later. Post your answers in the comments if you want to play along. A plane is standing on runway that can move (some sort of conveyor belt.) The plane moves in one direction, while the conveyor moves in the opposite direction. This conveyor has a control system that instantly tracks the plane speed and tunes the speed of the conveyor to be exactly the same (but in opposite direction). The question is: Will the plane take off or not? Will it accelerate and take off? Please comment/answer.
Replies: 6 People give a shit! Doesn't matter, wifey. All plane fly by either propellors, jet engines, rocket engines, or something of that nature. No plane are powered by their wheels. How would a plane like that fly? Posted by Dreqan @ 10/29/2006 04:30 PM PST Pookie, you forgot to mention that you're talking about a plane with jet engines, not a little Piper. It makes an important difference, I think. Posted by Wifey @ 10/29/2006 02:23 PM PST
The plane shouldn't take off. The speed of the plane isn't what creates the lift. The speed of the air beneath the wings (which would be unlikely to be accelerated enough by the conveyor) is what creates the lift. Posted by eric @ 10/29/2006 11:04 AM PST I do believe that would be a no. Posted by chad @ 10/27/2006 07:50 PM PST I'm gonna go with NO! Now I was an Aero E and a Comp E at one time, but I dropped out of both, so I don't know if that means I'm smart or stupid! Posted by Fangoria @ 10/26/2006 08:34 PM PST No, duh. Unless of course you wait half the time. Posted by Notta Engineer @ 10/26/2006 07:32 PM PST
