Plane on a treadmill poll...

[BKgen®]

The wheels are free spinning, the treadmill can be going 10 TIMES the speed of the plane and it still won't effect it any way, it will only make the wheels spin 10 times faster but the plane will still propel itself forward just like any other runway.

if i'm walking the wrong way down an escalator at the same speed as the escalator itself, will i go anywhere? NO.

but i might fly if i trip

Go down the escalator in roller skates the wrong way.

What powers your body? Your FEET! Just like a car is powered by it's wheels. Is an airplane powered by it's wheels, No. Is it powered by anything that touches the ground, no. The wheels are free spinning.

well, it's obvious that i've already won, but i'll humor you anyway.

Suppose a plane is on a runway that acts as a conveyer belt. The conveyor belt is as long as a typical runway. The plane moves in one direction, while the conveyer moves in the opposite direction at the same speed as the plane. The wheels of the plane are free-rolling. Will the plane be able to take off?

^^show me where it says anything in there about a power/thrust source.

It's an airplane, you know they have engines and that's what propels them forward, whether prop or jet it doesn't matter...both yield the exact same result.

so gliders have engines, too? never knew that.

No but gliders are towed into the air by a plane with a engine.

No but gliders are towed into the air by a plane with a engine.

then there would also have to be a tow-plane on the treadmill with the glider. the problem only says there's one plane.

you guys are completely missing the point here... even if the plane could move and keep up enough speed for flight, there is no air passing under the wings. Therefore: no lift. The damn plane could stay there allllllll day long, but never get airborne.

without moving air to create drag against the wings, there can be no flight.

what's so fucking hard to understand about that?


(It would probably work if there was a fan in front of the conveyer belt pushing against the plane.)

This thread from the very beginning, starting with the title, pertains to planes. Planes propel themselves, planes use runways, gliders use neither.

repped.

Why are you lauging, that vid proves you're wrong

You just proved it to yourself idiot.

If you walk down the escalator at the SAME speed as the escalator you will go nowhere.

If I come up behind you thought and PUSH you (thrust), you will travel the direction that I push you REGARDLESS of how fast yoru feet are moving.

Of course.. but then the treadmill would not be matching your speed anymore, lest it magically adjusted itself to the speed of the force of your push.
