Science! Busted!

Forum question posed: Would an airplane on a gigantic treadmill be able to takeoff?

Remember that?

PWNED

Welcome to a month ago.

I don’t think anyone did not expect this result, but they failed to answer my question:

What if the tread mill was going so fast that the plane could not overcome the friction that was being generated in its wheels?

what friction?  The friction that’s turning the free spinning wheels and nothing else?

Adam felt no resistance when he pushed the model car.  There is no friction to hold anything back when the accelerating force is applied against the air.

No, i’m talking about the friction that is present in any mechanical system. You have a moving wheel, no matter if its powered or free spinning, some how attached to a non moving surface, usually by some sort of bearing.

Proof: Take an airplane, apply force until its at speed X, and take that force away. The plan will eventually stop due to friction. If there was no friction, it would just continue forever.

Hence, there has to be some point where there is enough generated friction in the landing gear system that can’t be overcome by the propulsion systems of the plane.

Once the airplane hit 120mph though it would hit “terminal friction” and the speed of the aircraft would be free to increase while the relative elasticity of the normal force was inverted through a parabolic sine wave!!  DUH

Happy Anniversary btw
