[quote][i]Originally posted by Steve[/i] [quote][i]Originally posted by Cosmo[/i] [quote][i]Originally posted by Steve[/i] READ THESE TWO EXAMPLES TO SHOW HOW THE PLANE WOULD MOVE ON THE CONVEYOR BELT Think of it this way, push a toy car along a treadmill your arm will still move at the same rate and use the same amount of force to get it to the end as it would if the car were on a solid surface AND Ok when your running on a tread mill the only reason you go nowhere is becuase your legs are pushing against amn equal momentum in the opposite direction. Right, if you put some rollerskates on, on the treadmill, you would still be able to pull yourself to the end using your arms and a rope as easy as if you were on a fixed surface. To compare, the tread mill is the conveyor belt, the rollerskates and you are the plane and its wheels, the rope is the air, and your arms are the jets pushing against the air [Edited on 24-05-2006 by Steve] [/quote] I understand both of these...but where is the forward momentum coming from for the plane? As the question says, the converyor belt speeds up as the plane does, so technically there would be zero airflow over the wings and therefore no lift. [/quote] the forward momentum is coming from the jet engines just as it would normally. the speed of the conveyor belt is irrelevant as the wheels will just spin faster, the jet engines pushing against the air is fixed and not effected in anyway by the conveyor belt [/quote]
