This is the best gyroscope demonstration video I have found on KZread. In most videos I watched before, they just put the gyroscope on a flat desktop and let it spin. Thank you for moving the gyroscope and showing how the spin axis was consistent with its original direction.

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

But does the spinning wheel know where it is at all times ?

The spinning wheel knows where it is at all times. It knows this because it knows where it isn't, and by subtracting where it is, from where it isn't, or where it isn't, from where it is, whichever is greater, it obtains a difference, or deviation. The inertia equation uses deviations to generate force to drive the spinning wheel from a position where it is, back to a position where it was, and arriving at a position where it wasn't that that's where it shouldn't have been because intertia resists change, but it now is. Consequently, the position where it is should still be the position where is was but this is invalid for infinitesimal time, and so it follows that the position where it was, is now the position that it isn't. In the event of the position that it is in is not the position that it wasn't, the system has acquired a variation. The variation being the difference between where the wheel is, and where it wasn't. If variation is considered to be a significant factor, it too, may be corrected by the inertial torque. However, the wheel must also know where it was. The inertia of the wheel works as follows: Because a variation has modified some of the information the wheel has obtained by an external spinner, it is not sure just why a few fools are curling their fingers stretching their thumb, however it is sure where it isn't, within reason, and it knows where it was. It now subracts where it should be, from where it wasn't, or vice versa. By differentiating this from the algebraic sum of where it shouldn't be, and where it was. It is able to obtain a deviation, and a variation, which is called "Driving corckscrews in people's brains"

I understand how the missile know where it is now.

Modern aircraft use it too, just they tend to use laser gyros instead. Half of the fleet I fly is IRS equipped and the other half is AHRS, which is a modern equivalent of the IRS.

I think it's already clear how the gyroscope works -- the gyroscope knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is - whichever is greater - it obtains a difference, or deviation. Are you a jokester?

...actually I dicovered , all on my own, the prodigy of the gyroscope speculating on how possbily the bike could work....and I came up one day infering that I could have balanced myself keeping a rotating wheel up over my head....and then I discovered it was true and that struck me. BUT noonw had explained so neatly

Great video. Best demostration of a gyroscope I've seen on KZread.

PROFESSOR LEWIN IS FANTASTIC!!!

These gyro thingys say a lot more about this universe than we give them credit for.

That's science at work! Thanks for sharing Prof.

Best lesson EVER👍👍👍 What Wednesday?😅

This gyro doesn't have 3 degree of freedom. I can see that housing (yellow and red) allow the gyro to rotate only on two planes. Aviation experts would call them pitch and yaw. There is the black housing there as well. But the black one is not connected to any outer support with a joint allowing it to rotate around roll plane. I can undersdtand that human hands can to some extent function as a support of black housing that I am talking about, but in this case we can't call this gyro a free gyro. Free gyro should have 3 degree of freedom regardless of human intention to allow it to have the 3rd degree of freedom.

The inert shell has no space charge, but has the mass of a proton. It knows it's absolute position and tends to retain the same as Newton's law states. The orbital shell has the same charge as the protons within the nu-shell.

Excellent video. When there is no Gravity in space, how a gyroscope works without a Torque (due to gravity) and which forces are acting to activate it?

@greyengineer3153

6 жыл бұрын

that is the fallacy that most globe believers use to "prove" round Earth. Torque does NOT have to be from gravity. it can be from ANY push/pull on the mechanism. What you are referring to, is "unbalanced force". Therefore, a gyroscope WILL work in space, simply BECAUSE GRAVITY DOES NOT AFFECT IT!!! in "space" or freefall, or microgravity, etc, there would be even LESS friction on the bearings. kzread.info/dash/bejne/ioSJ16iYlKiphqw.html jump to: 33:27

And this is a "cheap" way to point satellites, such as Hubble, to new points in the sky. Rather than use expensive and limited fuel to fire small rocket motors/thrusters (and thereby also risk fouling the mirror with rocket motor exhaust, especially after many years of doing so), there are multiple gyroscopes which by remote control engineers add friction or breaking action on any one given wheel, which then moves the entire spacecraft to the desired new orientation.

Gravity free accurate motion is truly amazing

SUPERB. Camera quality is bit poor. Anyway thumbs up. My concept has never been that clear.

Putting this on my things to do list..if only, I could get my hands on a gyro. What's the problem with it? I don't understand - because I'm weak in passing physics.. And math. Can I deduce that a spinning object, breaks free from a magnetic field(earths magnetic field), and now has a movement off its own. The earth is spinning, - let's think of it as a spinning disk. What would happen if we put two spinning disk together? ..also, air friction and the weight off the axis would slightly tilt that spinning disk - as the axle slightly up tilt on the inner rim, hence making this experience have an error. What would happen if the weight was small, not to create much force on the axel, and the axel welded onto the disk.

Tilt a plane, and you create a fulcrum axis running through the plane while one side of the plane goes up and the other side goes down (a seesaw). That axis through the plane does not move because it is a pivot axis for the plane, but the mass in a spinning disc does move in many ways. The rotating and tilting mass that was initially motivated to go up must reverse its momentum at the fulcrum axis so it can start going down on the other side. The rotating and tilting mass that was initially motivated to go down must reverse its momentum at the fulcrum axis so it can start going up on the other side. REALIZE THAT! Mass must reverse its direction with each pass through the fulcrum (2 per rotation). Here's the kicker! It creates opposite forces on opposite sides of the rotation plane at the fulcrum axis. This starts the gyroscopic effect and is the CAUSE of the anomalous tilt, but here is the greatest part. When you tilt the plane and create a fulcrum axis that creates forces, and when the disc reacts to those forces, the reaction (anomalous tilt) creates a second fulcrum axis. That second fulcrum axis is perpendicular to the first and runs through the initiating tilting force. AND, the forces produced at this second fulcrum oppose the forces that produced the first fulcrum axis. Any input tilt gets inverted and push back out of a spinning mass. The mechanism at the fulcrum axis is better than the math at the spin axis. This is a momentum reality. The math puts all of the momentum in terms of the spin axis which makes math a successful orthogonal analogy.

Ok so how i am able to control my m4 6x recoil in my pubgm? In my phone.

My example of the anti verse. Postirons spin opposite to electrons. Via the atomic spin vectors and friction of quantum tanglment alongside nucleation. Were breaking into antiparticle symmetry. And eventually the data will be quantified. To show how wrong i am lol

Does it mean that a gyro would show a 90 degree angle tilt every 6 hours because of earth's rotation? After all you said "it's has no gravitational torque"...therefore it's independent of earth rotation. So the best experiment to prove to my friends that we live on a 1000mph spinning ball would be to set an experiment where I would have that spin for 6 hour and show the procession.

+Globe Skeptic Yes, I'm not an expert, but that sounds valid. I would imagine that it would be independent of the Earth's rotation, so they probably have an electronic device that compensates for it. It can tell you at any given time where the absolute position of the plane is independent of the globe.

+Globe Skeptic In airplane systems there s actually a small, continuous torque applied that makes it seek the local vertical. For this reason it resists short-term changes exactly as shown in this video, but also in the long term it adjusts itself to the local vertical. This corrects for not only the earth's rotation but also for long-range flights, where there is a significant difference in latitude and/or longitude between origin and destination, after which the gyro will still be properly aligned despite said difference. Google "gyroscope erection".

musclecar rocklover Thanks for naming it. For the life of me I'd not have recalled the exact name, as more than 20 years went by since I briefly studied this.
