Think Deep!

7 replies 1 views Edited Dec 13, 2006
Here's one for you guys:

If a commercial jet is on a giant tredmill, and the tredmill is set to the speed of the wheels, (so the plane doesn't move) and the plane gets faster and faster, will it take off?

I say no. I'll give you my reasons later. So what do you guys think?

No, because it's staying stationary. There needs to be air passing through the wings to create lift. Wheels spinning on an aircraft doesn't decide if it flies or not.

No, because the wheels are just spinning, the plane is never actually moving.

Ok. My reasons;

1) The plane is not actually moving. The tredmill is reversing the thrust given by the jets.
2) Because the jets on most commercial airliners are on the bottom of the wing, no wind passes over the top of the wing, which doesn't cause low pressure, which doesn't cause lift.
3)If it did leave the tredmill, it would instantly fall back to the ground, because planes can't hover.
