According to smackdown, yes it would be quite possible to stand the treadmill vertical then simply increase the spead of the treadmill. It would allow the plane to stand perfectly still and defy gravity in such the same way it would stand still and defy the thrust of it's engines when horizontal.
SMACKDOWN.
Please explain this.
What is to explain your right it would do that if the treadmill tracks the speed of the plane relitive to the treadmill surface. Assuming of courses the plane never loses contact with the treadmill. The torque of the wheels will simple increase until the force matches that of gravity.
So you are REALLY saying that the plane would hover in the air and not be pulled downward by gravity just because it's wheels are spinning?
AKA treadmill surface accelerates upward at 32ft/sec^2 and plane will stop acclerating downward at 32ft/sec^2 thereby defying gravity? With free spinning wheels??
Do you work for as an animator for Warner Bros by chance?
The treadmill's accleration would be alot greater then the accleration due to gravity. Because the treadmill is only acting thru torque on a very small part of the airplane.
Explain.
It doesnt matter, his explanation is wrong. by his interpretation the torque would increase to infinity and the plane would be thrown backwards at infinity miles an hour in 0 seconds. its pure bullsh!t that the torque would match anything. the treadmill will never stop accelerating because it can never match the speed of the airplane relative to its own surface.
No the control system would balance the torque from the wheels and the force from the plane so that it doesn't move.
I think I'm getting close to proving all you fools wrong. So you agree that the treadmill can apply a force to the wheels? Ok now just added the control sustem which will balance the force from the treadmill with the force from the engine and the plane will not move.
haha "getting close to proving all you fools wrong". I really got a LOL out of that one. It's so fun to feed the trolls because every once in a while they do/say such funny things or perform some neat little monkey trick in exchange for the morsel.
But anyway..
The treadmill applies force to the wheel of course via friction. The wheel does not apply the same force to the landing gear unless you apply the parking brake...that's what ball bearings are intended to prevent.
So given a free rolling wheel how does the rotation translate into enough force to make a plane hover in mid air?
If I take the same wheel separate from a plane or treadmill and just spin it real fast does it hover in mid air?
Everyone has of course seen the whole inertia trick where a spinning wheel (like a gyroscope) will *resist* motion but I've never seen a gyroscope or airplane wheel magically just start floating up in the air and then off into the distance.
Are you SURE you don't work as an animator for Warner Brothers? I swore I've seen Wyle E Coyote run real fast so it lets him hover in mid air after he left the cliff edge.
