Lets call Big Mike and ask him turn around and go uphill.
Umbrella ain't puffed up at all nor is his arm holding any resistance.....but

According to the law of physics that’s not possible

It is if you're going downhill...

That is true!

OK so where is the skateboard on a treadmill I ask?

It goes back to a long time forum argument about a plane on a treadmill

 

[Spudsbud]

Ohh it will fly.........

 

[4Waters]

Ohh it will fly.........

I don't see why not

 

[WYRD]

I don't see why not

No way it won't generate lift

 

[4Waters]

No way it won't generate lift

Why not? If it's traveling at min take off speed it should create lift. LOL

 

[Nordie]

Here we go again...

I planted the seed now time to watch it grow LOL

There's Racey sharing RDP folklore with the world


As for the blower powered umbrella skateboard

 

[beaverretriever]

Let's end this now as I can't bear to see the morons out in force again.

Yes, a plane can take off on a treadmill. Only caveat being that the treadmill is long enough for the plane to gather speed. Other than that, it will take off. Remember folks, planes dont move forward from drive wheels; they move forward from thrust pushing against the atmosphere. Doesn't matter if they are taking off from a treadmill or an ice rink.

 

[Racey]

If you put a giant fan on the back of a sailboat and aim it forward to blow into the sails, will it move forward?

Negative ghost rider. Planes fly because of lift created by the wing. No airspeed on wing, no lift. The treadmill is assuming to erase forward speed of the wheels. Wheels just spinning faster does not create lift. No different than walking against an escalator.....I think?

@Instigator don't start with me...

Whoever said a plane won't leave the ground because there is no lift? I think we all understand a plane needs a certain amount of forward speed to gain lift. Man, planes do not move forward because the wheels are driving, they move forward because of the thrust from the engines. Doesn't matter which way the surface is moving.

I seriously can't believe anyone would debate this.

First Racey shares the folk lore and now the Beav ends the "discussion" - how things have changed around here

Doesn't it depend on if the treadmill is spinning as fast as the wheels so the plane stays stationary? (Putting water on the seeds WYRD planted)

This should help you figure it out

So, people who go with interpretation #3 notice immediately that the plane cannot move and keep trying to condescendingly explain to the #2 crowd that nothing they say changes the basic facts of the problem. The #2 crowd is busy explaining to the #3 crowd that planes aren’t driven by their wheels. Of course, this being the internet, there’s also a #4 crowd loudly arguing that even if the plane was able to move, it couldn’t have been what hit the Pentagon. What about those going with #1? Don't ask.

This should help:

Neither can I. Specially from a guy with an FTP as high as yours. (This is Nganga, changed screen name)

I hate it when my shoe lace gets a knot in it

Holy crap, are you building a new Skater?

 

[Nordie]

We should see if those Mythbusters guys can solve this.

 

[28Eliminator]

Lol... you can tell who all the "newbies" are

 

[Skater368]

Skater 368, from the beginning.

Been meaning to put this up for a while. Most know that building a Skater isn't a short process. Long periods of time go by with seemingly no progress, so updating a build thread would prove slow. There's been enough behind the build now, progress is moving well. The boat is supposed to be in...

Yes sir. Be done in a week or two.

Bring on the 2x blower to make it up the hill...

 

[SnoC653]

Since the belt on the tread mill will cause some air movement due to surface friction. In theory if the treadmill could turn fast enough and the wheels didn't get so hot they burned the plane down, it could take off. But in theory, almost anything is possible. Look how much you can tow with a F150.

If you're driving down the road in you're three wheeled canoe, and the fourth wheel falls off, How many bricks does it take to build the CN Tower? None... because there are no bones in ice cream and no chocolate chips in chicken...

 

[WhatExit?]

After we solve the airplane on a treadmill what about this one...

If an F150 is moving forward at 60 MPH (not towing) and a ball is shot out the back at 60 MPH what happens to the ball?

It hits Big Mike in the head at 120 mph, knocking him of his skateboard.
Ohh wait... did we solve the plane/treadmill mystery?

 

[Kachina26]

They did, and it took off.

 

[Nordie]

They did, and it took off.

I edited my original post

 

[t&y]

IT IS FACT NOW!

The pilots comments at the end scares the shit out of me. Hopefully he only fly's solo.

Can't happen F-150s don't have balls

It will fly right into the wall

I see it differently. I see the plane being thrown into the air by the treadmill. And what do you think is actually propelling a plane on an aircraft carrier catapult? It sure as hell isn't the plane. Its being thrown by the catapult, that's what they do, they throw things.
