please lord make it stop. IIIhorn you are the toughest poster i know. how you sat through all of this twice is beyond me

so do a recap for me

exactly how is the experiment going to work?

The whole point is if the plane and conveyor at traveling at the same speed but in opposite directions - the plane wont take off b/c it can't get any speed.

This thread got out of hand.

yes it will take off.

dear god, please tell me that you don't actually believe that it won't take off.

I thought that was the point of the thread?

Gambo, here is the original query:

"A plane is standing on a runway that can move (some sort of band conveyer). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in the opposite direction). Can the plane take off?"

How does this prevent the plane from taking off?

That doesn't even make sense. If the plane's speed is 0, than the conveyor's speed is 0. If the plane's speed is 175 knots than the conveyor's speed is 175 knots, but the plane (most smaller planes) has enough speed to take off.

but flaith

if im reading this right...to put it in simple words

the plane is traveling to the right at x mph

the belt is moving to the left at x mph

so effectively the plane is standing in place

so if there is no movement with the airplane with respect to the ground

how in the hell is there enough force to lift it?

The plane is not moving if both conveyor and plane are the same speed in opposite directions.

I don't need any explanation from you fancy-pants engineers.

I guess gambo has never understood the wheel.

The plane is moving or the wheels? That's an important distinction.


And don't ever call me an engineer again!

The plane is mute.

the plane cant talk?

If it could talk it would just ask to be taken off the conveyor.

It's plane spoken.

the ****ing trick to the question is that people ignore the fact that the plane is not being held in place. THAT IS THE WHOLE POINT OF THE QUESTION! and you fools that don't understand the plane will take off are ignoring the core aspect of the problem

gambo... look at my FBD on page 9


the most important thing to remember is that, unlike a car, which propels itself through the force on the tires, the plane uses its engines to combust the air and force it backwards.... the wheels merely provide a nearly-frictionless medium on which the plane can translate.

Umm...it is being held in place - just like I get held in place by a treadmill.

Aren't you an engineer?

The conveyor will only increase wheel rpm.

Nothing more ... nothing less.

The conveyor is moot!
