How does the gyroscope adjust to the actual level of the earth beneath the plane?

[Anonymous No.9724434]

I don't think you understand whta the picture is about
The gyroscope will keep its position relative to the stars, so the question is how can it tell the level relaive to the earth below as it moves around the earth?

Your statement has no relevance to the picture. You don't understand how a gyroscope works

[Anonymous No.9724479]

>>9724470
Won't it?
I understand that aviation instruments like artificial horizons have mechanisms to correct the gyroscope's orientation so it's always perpendicular to the vector of gravity (down)
But a plain old gyroscope would seem to rotate relative to the surface of the earth as it goes around the globe because it keeps its original position relative to space, right?
Right?

The gyroscope keeps its orientation once spun up. It is conservation of angular momentum.

Yes.
I answered this a few months ago.
A gyro is fixed to the stars (or the inertial frame). It will rotate as you travel around the Earth or even if you sit still, because the Earth rotates.
Autopilots have correction mechanisms. (Early ones didn't have it because the "drift" was high enough that they required frequent manual correction anyway.)

The gyro will turn for the same reason a Foucault pendulum does.

[Anonymous No.9724564]

>>9724431
It doesn't, it just keeps the plane stable

The accelerometer, the thingy that measures gravity and acceleration is used to figure out which way is down

Would the gyroscope do the same thing aboard the ISS?

The earth is a flat plane - that's why aeroplanes are called planes, they do not need to dip their nose down every so often to account for the curvature. Case closed.

[Anonymous No.9724612]

>>9724570
Yes, a gyro will appear (from the viewpoint of an astronaut floating next to the rotor) to change orientation, making a complete turn every 90 minutes or so.
I don't even know if the ISS uses mechanical gyros. NMR gyroscopes and ring-lasers are more accurate and have fewer parts to go wrong.

[Anonymous No.9724614]

>>9724431
The object in OP's picture looks like a spinning top, not gyroscope. Tops act differently from gyroscopes. A gyroscope is mounted in gimbals which lets it rotate freely under gravity without gravity applying a torque to the top, which prevents gyroscopic precession that would make the top in OP's pic would rotate around its point(contact with surface) once it's center of gravity is no longer over's its point.

>>9724570
A spinning top in free-fall on the ISS would actually act like a gyroscope, so yes and no i guess: The spinning top in OP's pic would not act the same way on a plane and in free fall, but a gyroscope would act the same.

Everyone in this thread seem's to think that rotating objects have gravity defying powers.

[Anonymous No.9724632]

>>9724571
So when you fly directly east you are flying in a circle around the north pole. You would have to turn the plane slighty in order to continue moving east. This means that at different latitudes a trip around the world will take different amounts of time. Let's test it.

THIS.
OP's pic shows an aircraft traversing a significant part of the Earth's curve.
The inconsistency of your average gyroscope over such a long time/distance probably outweighs the other factors involved.

A simple gyroscope with full range of motion would tend to maintain orientation with respect to the stars. But this unit would also collect errors over time and wouldn't maintain that axis for a long period.

A traditional spinning airplane gyroscope has a mechanism inside that assumes the aircraft is flying level most of the time. The local gravity vector opens vanes that allow air forces to push it slightly. These forces cause the gyro to precess in exactly the direction that causes it to align with the gravity vector.

Modern ring gyroscopes don't erect in the same method, but still require compensation methods for accumulation errors over time.

In order to let the gyro very slowly orient itself to the direction of gravity while in operation, the typical vacuum powered gyro has small pendulums on the rotor casing that partially cover air holes. When the gyro is out of level with respect to the direction of gravity, the pendulums will swing in the direction of gravity and either uncover or cover the holes, such that air is allowed or prevented from jetting out of the holes, and thereby applying a small force to orient the gyro towards the direction of gravity. Electric powered gyros may have different mechanisms to achieve a similar effect.[9] The problem with these leveling mechanisms is that they will respond not only to gravity but to accelerations in other directions due to other causes, such as turns. If the gyro simply immediately oriented itself to the net acceleration vector, then it would be useless. So these adjustment mechanisms act to right the gyro very slowly, such as 2 to 8 degrees per minute, in the hopes that the gyro will stay nearly stable during any brief maneuvering, and that most of the time the aircraft will be flying in a steady, non-accelerating manner so that the gyro has a chance to orient to gravity.

Because it's a local sun that moves closer and further away. If it's too far away then you cannot see it, it will be below the horizon line due to perspective's convergence merging everything into the horizon line.

Perspective does, particularly over water as that creates a mirroring effect that obscures and distorts the object as it moves further away and blends into the horizon (Note: It does not go beneath anything).

[Anonymous No.9727486]

>>9727481
Well, what tends to be left out about Eratosthenes is that he concluded either the earth was a globe with a distant sun, or a flat plane with a local sun orbiting above us. Observation tells us the sun is local.

[Anonymous No.9727496]

>>9727486
No they don’t, sorry. A local sun would change in angular diameter for everyone that can see it every hour. It doesn’t, so it’s impossible for it to be local.

[Anonymous No.9727499]

[Anonymous No.9727511]

>>9727506
No it doesn’t, and it only appears to get smaller at sunset. There is no change whatsoever in the sun’s angular diameter between 12 PM and 3 PM when there should be in your retarded model, and the only change in the sun’s angular diameter whatsoever is less than a degree and occurs over the year due to earth’s small orbital eccentricity.

Here's the deal: there are three types of Flat Earthers who have regularly posted to 4Chan: prankster intellectuals who troll to test your knowledge and debate skills, literal Bible interpreters, and recently the most proliferate: the juvenile-level troller.

None of them provide any evidence of phenomena that *require* a flat Earth model to explain, but rather place the onus on you to prove the round Earth (again, and again, and again, ...) while disavowing any science or proofs put forward. They will post memes that ostensibly 'prove' some flaw in the round Earth model, but containing geometry, maths, logic, and facts so absurdly wrong that you are compelled to display your superior intelligence and knowledge. Mostly though they will provoke you with the classic, "If you don't respond, you're a faggot and you prove me right." By responding, you've taken the bait.

They don't care whether the Earth is flat or round. Trolls await your posts (reasoned or prefereably emotional) and meet them with insulting or provocative responses, because it's about the lulz from getting you to respond. If you reference web-based information (that they could have looked up, had they interest) they will accuse you of being a shill for some absurd conspiracy.

It is simply impossible to keep up with having to explain away the barrage of stupid posts, and the anonymous mask of 4Chan removes culpability for the prankster and enables this crap. Arguing is akin to painting over mud - you just end up with a dirty brush.
