  • Stump BDR

    Ok, some one give me a question, if you stump me then I will CP you, However, If I get that question right I would request CP from you instead. Clear? GO! if you highjack this thread you owe me 20 CP. that is all.

      There is a variation on this riddle that says that the conveyor belt matches the speed of the plane. It doesn’t matter… the plane still takes off. The conveyor belt could be going 5 times as fast as the plane, and the plane would still take off.

        What... is the air-speed velocity of an unladen swallow?

          Answer me these questions three!

          WHAAAT...is your name?
          WHAAAT...is your favourite colour?
          WHAAAT...is the capital of Assyria?

            Wait, how does that work? If the plane is essentially not moving forward, how can it take off?

              It's not the net speed which matters, it's just the speed of the plane, and when it reaches the lift off speed on the conveyor belt it'll still take off because of the thrust generated by the engines as the plane is still essentially moving forward, the net velocity doesn't matter, only the plane velocity.

                Are we talking African or European swallows?
                Victory and defeat are matters of the temporary force of circumstance.

                  But I thought that the ability of planes to fly was dependent upon air lifting the plane. If the plane is essentially not moving, then the wings will not be cutting through the air, and thus, no lift.

                  The solution is confusing.

                    That's correct... planes manage airflight due to lift of the air pressure... which is from the air moving faster over the wings than it is moving under the wings. So unless the conveyer belt is also moving all the air with it, I don't buy this explaination.

                        You get a beach hut! (Natural) Log cabin + c That's an olllld one :p To a mathemagician, obviously/

                        If I were sin squared and you were cos squared, then why would we be the perfect couple?

                          It's the speed of the air moving past the wings that matters.


                          STUMPER:

                          Solve the following differential equation using a Laplace transformation:

                          Code:
                           dy 
                          ----  + y = x^2 - d(x-2)
                           dx
                          where d(x-a) is a dirac delta function and y(0)=0 and y'(0)=0.

                              It makes me feel a little better that you agree with me.
