You have a plane and a conveyor belt.

[Suspicious-Teach8788]

Option 1 and Option 2 dont matter.

How fast the wheels spin does not change a THING.

You could have the conveyor belt doing close to the speed of light and the plane would take off the same way. Oh whoops. That's where relativity comes in. But still, spinning of the wheels is an illusion to make you think it's not moving, but in reality it means jack sh!t.

It actually can do some things, highly unrealistic things. If you spin the wheels faster and faster rotational inertia and friction can both become problems.

Minimal issue. The biggest problem is the tires would blow right off. But when you get into scenarios where a treadmill can do rediculous speeds, you can have tires that don't blow off and bearings that do not create much friction.

There are four basic forces at work in order for an aircraft to be in flight... Lift, Thrust, Gravity, and Drag. The conveyor belt would not give enough thrust nor provide enough lift for the aircraft to take flight. There has to be a great enough force or momentum to create lift in the wings... air would then be creating the much needed lift hence "upwash or downwash"....

. . . or even a 'washout'


Next puzzle:

You have Al Gore on a conveyor belt, and for every step forward he invents another internet.
With unlimited access, how many internets could Al Gore invent before he falls offf of the conveyor belt?

This is getting funny now. I think there's two or three groups on the go in here:

1) People who are taking the p!ss, realise the plane will take off but are making up prank theories as to why it wouldn't.
2) People who like to show off their knowledge of physics, get suckered in by 1) and go on and on getting worked up.
3) People who are really, really stupid and actually believe the plane soulen't take off.

As for above treadmill/rope analogy, it makes sence, but maybe the tards are confused because it's a rope. Maybe replacing the rope with a kite and a tail wind would be more accurate/easier to understand?

Also, the treadmill 'matching speed' is an impossibility. As the aircraft moved along, the speed of the wheels/treadmill would swiftly move up to infinite speed (which is impossible) - if the plane is moving forward, the wheels will always be n+1 the speed of the conveyor, which would therefore speed up to match this, and so on....

British coloquial....they don't even know WTF they're saying half the time.

How about all the intelligent people stop responding to this thread, that way the retards who think the plane won't take off will eventually get bored of agreeing with each other and stop posting in this thread. That way I don't have to be angry every time I see this piece of sh*t being bumped to the top.

Hmmm... I get were some of the more intelligent arguements for the plane not taking off are coming from.

If you take the problem LITERALLY:
"The conveyor belt matches the speed of the plane's wheel"
For the plane to take off, the wheels will HAVE to spin faster than the conveyor belt. This will not happen given the conditions of the problem. Therefore, the problem itself is presupposing a condition that cannot be met given the setup of the experiment.

If someone would just make an illustrative animated gif or something, that would be /thread.

They'd screw it up.
