MYTH BUSTERS IS GOING TO SEE IF A PLANE TAKES OF FROM A TREADMILL

That would be the biggest waste of everyone's time. Lift is caused by air moving over the wings. No plane movement = no lift. You have to have forward motion. Unless of course they sent the plane moving on the belt (such as if you were to just stop running while the treadmill is moving) and create lift that way.

why wouldn't the plane move? THe wheels have nothing to do with the plane moving forward, the propeller or jet does. So the minute the thing fired up it would fly off the tread mill.

I ran backwards on a stationary treadmill belt the whole winter and improved my 5k time 40 seconds because of this phenomenon.

Congrats, but did you achieve take-off?

Hey guys, big news, Dathan Ritzenhein is moving to Eugene.

You haven't been around very long, have you?

I hear next week they're entering Teg in a 10K.

and then they are going to see what would happen if pearl harbor is ever attacked

Are you guys retarded or what?There is no way it can take off.

You, Tarf, are the retard. Stop being such a pessimist. You smell.

So prove it can take off pinhead.

The trick to this is understanding the difference between how cars and planes propel themselves. A car with wings on it set on a treadmill that matches it's speed would not move forward, but a plane would. This is because a car propels itself using the ground to move forward, while a plane's engines propel it through the AIR.

You dumbasses will realize it's possible on wednesday I suppose.

Oh boy. The plane does move!

If the treadmill truly matched the speed of the wheels of a plane, it still would never move forward or up. Yes, a plane's engines propel the plane through the air, and on the ground as well, but it requires windspeed to get in the air. If the treadmill truly matches the speed that the plane is moving/rolling/being propelled during it's attempted takeoff, the plane would be standing still in relation to the air.

That is, if the rockets propel the plane to 500 mph, and the treadmill instantly reacted to be at 500 mph, the plane would still be in the same spot in relation to the air, and would not work up the windspeed to take off.

If a plane ever moves forward on a treadmill, then the treadmill speed is not really matching the speed of the wheels of the plane. If the experiment is set up in a manner that allows the plane to move faster than the speed of a treadmill, then it is feasible that it could take off.

It doesn't matter how fast the wheels move. the plane will move forward. the wheels will move faster than the treadmill because it will move forward.think of a tricyle if the front wheel were on a tread mill and the front wheel were allowed to move freely the front wheel could spin at 1000 miles an hour and the trike would not move. If the back wheels providered locomotive force to move forwrad the front wheel would move forward regardless of the speed of its rotation. That rotation would be faster than the tradmill and it would move forward. A plane force of motion/ is independant of its wheels so it will move forward much like the tricycle.

I must be really bored to want to explain this.

No, if the rocket propels the plane to 500mph and the treadmill instantly reacts to 500 mph, the plane will still move forward at 500mph, but the wheels would be spinning at 1000mph.

Of course and well explained. But to be honest in the previous thread it took me to the 43rd post (I think) before I finally got this concept.

Yes. Just because the treadmill is moving doesn't mean that all the air above it moves. The air above the moving treadmill will be just like the air moving above any other runway.

Same with me. THe plane will take off because it moves independently of the wheels like has pointed out before.

This was supposed to be on Mythbusters before.
