ORIGINAL: Wes The Mess 15thAF--thats what i was saying about spooky action at a distance...the conveyer belt and the wheels spin simultaneously to compensate for the engine thrust--in order for the plane to move forward, the wheels must be moving faster than the conveyer belt, right?...but since the wheels and the conveyer belt spin at the same speed, the wheels can not move faster which means the plane can not move forward--if you want, i can explain it like i would to a 3 year old...if you run on a treadmill and you run off the front of the treadmill, the reason is because you were running faster than it, right? but if you start to run faster and push the speed up button at the same time, you will stay on the treadmill because you are running faster and the treadmill is moving faster simply put, without time travel, theoretically this experiment would not even be possible to conduct--so you are right and i did think of this as i was typing which is why i put all that junk in parenthesis and said i assumed there was no spooky action at a distance or time travel involved so the experiment was possible--if you had quoted a little more you might have been able to figure this out CHassan--there will be a point where the wheels stop accelerating, when the engine reaches maximum rpms and cant push any harder so the wheels dont have to spin faster to compensate for more thrust because there is no more thrust--oh, and if the wheels never actually did stop accelerating, the cosmic shift would only cause jupiter to smash into the surface of the earth between the months of july and december because of the gravity of the sun and location of the planets...between january and june, it can be either neptune or saturn that get pulled onto a collision course with earth and if it is february 29th on a leap year, the universe will most likely implode because the cosmic shift would have nothing to pull and therefore would pull space--so for any of you who want to attempt this stunt, please do not try it on february 29th... If the engine is tied to a test stand, lets say it produces 10lbs of thrust. Does it ever stop producing 10lbs of thrust? So if 10 lbs of thrust will move a plane at 10mph IAS and the plane never reaches 10mph IAS does it ever stop trying?? Nope so you will never reach a point where the wheels stop accelerating. If you do the engine will still be trying to move the plane through the air at 10mph IAS. Now if the wheels do stop spinning they will ba at a VERY high rate of rotation. Every little bump, vibration, of nuance on the conveyor or treads will cause a loss of friction between the tire and the surface of the conveyor. At some point I'd be willing to bet that the tire, due to this loss of friction, will begin to skid. Once it starts skidding the plane will have the ablility to advance down the runway and reach take off speed.
