I Have a Question :-)

I'm no pilot (yet) but I guessed on that because if you were going straight up then the wing would have any lift and you'd need to gain some lateral speed, or forward air movement over the wing to get lift, and that could come from a dive, right? or would the elevators be effective in a vertical climb like that?

How are you going to dive when the plane in the problem has zero airspeed, equaling zero lift, equaling the plane still sitting on the runway?:goofy:

No chance the plane will take off. Its a treadmill! The wheels are moving too fast in the wrong direction.

In that case you can't go uphill being pulled on a ski resort T-bar if the snow under your skis starts sliding downhill, right? :no:

actually, it wouldn't have to avalanche - the snow is already moving under your feet as fast as you are going uphill! And if the t-bar were moving as fast as lift-off speed, and you had wings, why you'd go up in the air!

Just be sure you let go of the t-bar at the top or you will fly! Not far and not efficiently but you will fly. :)
 
THAT would be the least of my worries! I'd be on top of a mountain, in snow, on skis - for the likes of me, that would be a much worse problem, I assure you! :eek:

I was thinking a vertical takeoff of a vertical treadmill, and one you have sufficient altitude then you would, but I now know that you don't need to dive to get moving laterally.

one end on the plane... the other on.. the sun? gravity?
