So if an airplane tries to take off from a large conveyor belt ....

[skibreeze]

Fug, not again!!

thrust isn't restricted by conveyor, thrust creates air speed, air speed creates lift, wa la it flies.

NO! Because the wheels have drag and therfore the plane will go backwards.

 

[skibreeze]

Oh yeah, how could I forget that the engine couldn't overcome wheel bearing friction.

What happens when the wheels get so hot from friction they explode?

 

[sledsrock]

It'll fly........here we go again.

If you are running on a treadmill do you feel wind? Of course not because you are not moving, so it is safe to say it can't fly because it needs lift (wind) to take off.

I'm sorry but you guys are all wrong, you are ALL missing a crutial peice of information, is Chuck Norris onboard? Because if he is onboard, and the airplane doesn't take off, he will be sooooo mad that due to the math equation E=MC2, the universe will implode causing the death of every living being, except Chuck Norris, of course.

I think its only fitting that my first post on the new forum is to the mess that I started on this topic...

A better question is:
Will an XP beat a Dragon on a conveyor belt?


ps- the plane will fly and those that think it wont can stick to mowing lawns and leave the physics to the professionals

Will an XP beat a Dragon on a conveyor belt?

That depends, are there any pine cones on this conveyer belt? If there is the XP definitly won't win as the PCDS will shut the motor down before it has a chance to move. Even if there isn't any pine cones on the conveyer belt, the Dragon will still win. Dragons fly and make XP owner's cry!

And didn't you start the topic as "look at these idiots on a skateboarder forum arguing about this!" or something like that. Then it kinda exploded over here. Thanks for the memories dude!

ya, but the plane STILL flies

 

[Meatman]

lift is not created by thrust if the object isnt moving....the wheels are moving....the plane isnt....i do think i saw 2 more votes for spontaneous combustion though

 

[bonz50]

i'll say it one last time from the cheap seats....

DIRECTIONAL THRUST IS GENERATED INDEPENDENT OF HOW FAST THE WHEELS ARE MOVING, DOESN'T MATTER IF THE WHEELS ARE TURNING AT 1,000,000 MPH, THE JET ENGINE CAN GENERATE FORWARD MOVEMENT REGARDLESS

until it explodes anyway...

 

[buckshaut]

im going with it flies for the same reason the wheels are free to spin and the thrust is against the air

 

[BuffriderNP]

Asuming that the tredmill is going the same way that the plane is pointed and the brakes are on. Then the plane would move and it should gererate lift!

 

[HeadLever]

Damn, I was going to post my free body diagaram, but the size is 1.8 KB over the new image limit. I don't feel like compressing it now, but if we get to Page 8, I may have to.

 

[nps RMK]

i think it will stop the space time continum

Not if the plane is properly equipped with the flux capacitor, because as we all know, the flux capacitor is what makes time travel possible.

 

[winter brew]

This was probably my all time favorite thread, Bonz 50 has it right, it flies no problem, it accelerates in relation to the surrounding atmosphere (since that is what the engine developes thrust against) just as it would on a runway, conveyor, water or jello. The aircraft engineers I work with got a kick out of some of the responses from the "no" crowd.

 

[Shifty]

wow all this rant and I dont even have a plane

Ya, we got a whole load of fuggin' rocket scientists on here.
