In this video I go over how a gyrocompass works, my own unique explanation of gyroscopic precession, and several corrections to my earlier videos. A gyrocompass is just a spinning wheel with 2 degrees of freedom and a mechanism to induce precession as the Earth rotates, thus allowing it to detect True North. Compare this with a gyroscope that has 3 degrees of freedom. Gyroscopes have 2 main properties: rigidity in space and precession, which is the change of direction of its spin axis.

In mainstream physics, precession is explained by the right hand rule: curl your right hand along the direction of the gyro spin with thumb pointing outwards, do the same for the applied torque, and the direction of precession follows the vector sum of the directions of the thumbs. In MES physics, I explain precession as the gyro spin and applied torques want to line up with each other, and that precession itself is a torque that can cause the gyro to rise upwards against gravity.

Gyrocompasses require an additional precession mechanism because the Earth rotates very slowly, so friction in the bearings typically can overcome precession due to Earth's rotation alone. One mechanism of inducing precession is by attaching a mercury tube to the gyro such that as the gyro lifts the tube due to its rigidity in space, the liquid mercury flows to the opposite side. This induces precession such that the gyro will spin opposite of Earth's rotation. Another mechanism is by simply adding a weight to the bottom of the gyrocompass: as the gyro lifts the weight, there is a downwards force by the weight that induces precession such that the gyrocompass aligns in the same direction as Earth's rotation.

Further in the video, I clarify some errors I made in my previous videos. The gyrocompass explanation image I showed previously was actually correct and my edits were wrong. The compensator weights in the WW2 gyrocompass video I went over were used to balance the weight of the gyro and not to induce precession; it too used a mercury tube setup which they referred to as a "mercury ballistic".

How Gyrocompasses Work + Corrections to Earlier Videos

Gyrocompass Corrections.jpeg

MES Note

I started doing Debunking Flat Earth videos and the first videos were on the gyrocompass.

After making those videos, I realized that I made some slight errors regarding gyrocompasses so I will clarify those here.

Note also that I will update the relevant video playlists to include this correction, and those can be seen on MES Links: https://mes.fm/links

How Gyrocompasses Work

A gyrocompass is a spinning wheel with 2 degrees of freedom and a mechanism to induce precession to determine True North (or geographic north). A gyroscope is a spinning wheel with 3 degrees of freedom.

GIF: Free gyroscope can be rotated about 3 different axis.

Image: A spinning wheel with 2 degrees of freedom instead of 3. Technically this is a gyrocompass but this doesn't have a mechanism to induce precession.


Gyroscope Properties

Gyroscopes have 2 main properties:

  1. Rigidity in space
  2. Precession

Rigidity in Space

Gyroscopes want to maintain their orientation when torqued. Torque is a "rotational force" or pair of forces that cause a turning motion.

Image: Torque as a force-couple.

Image: Torquing a car tire nut.

Here is a demonstration of a gyroscope resisting changes in its orientation.

Precession

Precession is a change of the rotational axis of a rotating object.

In mainstream physics, precession is explained by the Right Hand Rule.

image.png

Image: A spinning wheel precesses in the direction as per the right hand rule.

image.png

GIF: Mainstream demonstration of precession that ignores friction at the base or gyroscopes rising on their own.

In MES physics, precession is explained as the spin and applied torques wanting to line up with each other, even if it means rising against gravity.

image.png

This is demonstrated in the following experiment, which shows the downwards torque causing precession in the counterclockwise direction (since the gyro is also spinning counterclockwise), and precession itself acts as a torque to keep the gyroscope upright and rising. Again, all this until the gyroscope lines up with precession / applied torque.

image.png

MES Experiment 5: Gyroscopes precess upwards on ice with zero centripetal force.

Further demonstrations can be seen in a gyrocompass-type setup: https://youtu.be/1kOL6qQf6I0

image.png

Torquing the gyro will cause it to want to align spin and torque directions.

image.png

Torquing in the direction of spin is stable.

image.png

Torquing in the opposite direction of spin is unstable and any deviations from horizontal will induce precession and cause the gyro to flip upside down.

image.png

Pushing the gyro down will cause it to precess so that it spins downwards.

image.png

Once the gyro tilts so that it flips over, a downwards force reverses precession direction, but still wanting to align spin and precession directions.

Important Note: High Spin Speeds Overcome Small Torques

Note that in the case of the free gyroscope with 3 degrees of rotational freedom, the bearings provide very little torque hence the gyroscope will barely precess as the casings are turned.

If a gyroscope is spinning fast, then the gyro will precess slowly.

image.png

MES Experiment 2: The gyroscope on the left is spinning fast and precessing slow. The gyroscope on the right is spinning slow but precessing fast.

Theoretically, if a gyroscope is spinning VERY fast, then it will appear to be not precessing at all. Thus, even the gyro spinning top above will act like a free gyroscope.


How Gyrocompasses Detect True North

Theoretically, a gyrocompass can detect True North without any additional mechanisms to induce precession since gyroscopes want to align with applied torques.

Image: Theoretical gyrocompass without additional mechanisms to induce precession.

MES Experiment 31: Theoretical gyrocompasses with only 1 degree of freedom.

image.png

Video: Theoretical gyrocompasses with Earth imposed in between.

But since Earth rotates very slowly, the induced precession would either be incredibly slow or too small to overcome friction and other constraints. And certainly not basic store bought gyrocompass-like setups with direct metal to metal supports with NO bearings, as these Flat Earth disinfo agents would have you believe…

image.png

Video: Flat Earth disinfo agents discussing a useless "gyrocompass" experiment with high friction connections that would be able to detect Earth's rotation even if it was 1000 times faster (literally).

Here is a demonstration of the same "gyrocompass" as above and showing that it can't detect slow rotations (since static friction is higher than dynamic friction).

image.png

Video: Gyrocompass Can't Detect Slow Rotations Due to High Static Friction

My above gyrocompass couldn't detect a rotation of 1 revolution per 2 minutes (rough estimate). Compare that with Earth's rotation:

1 revolution per 24 hours.

10X faster is 1 revolution per 2.4 hours.
100X faster is 1 revolution per 0.24 hours = 0.24*60 = 14.4 minutes.
1000X faster is 1.44 minutes which is just faster than our slow rotation!

Thus there needs to be an additional mechanism to induce precession and speed up the gyro alignment with the rotation of the Earth; or alternatively produce literally frictionless bearings.

One such method is to add a tube of mercury that shifts its position as the gyrocompass lifts the tube trying to maintain orientation.

image.png

Image: The mercury causes a downwards force on the left side, thus causing precession such that spin lines up with the downwards force. Thus, in this case the gyro rotates counterclockwise and OPPOSITE of Earth's rotation.

The following image shows a gyrocompass with and without the mercury tube. Note that this image is indeed CORRECT and that the image I used in my earlier videos is WRONG. And the gyrocompass without the tube is NOT a free gyroscope as I incorrectly stated before.

image.png

Image: Gyrocompass without the mercury tube wants to maintain orientation (above). Gyrocompass with a mercury tube wants to align OPPOSITE of Earth's rotation.

Alternatively, adding a weight at the bottom of the gyrocompass will torque it downwards such that the gyro will precess to align WITH Earth's rotation.

image.png

Video: Inducing precession in a gyrocompass by adding a weight at the bottom causes the gyrocompass to align in the direction of the Earth's rotation.

This is pretty much how a gyrocompass works, but further technical operating details can be found at the Steering Mariners YouTube channel.


Further Corrections to My Earlier Videos

As stated earlier, here the image I used to explain gyrocompasses that has my WRONG "corrections" applied to it.

image.png

Image: The MES Notes in red are WRONG. The unedited photo is correct to show the gyrocompass aligns opposite of Earth's rotation.

Another error I made in my earlier videos was stating that the compensator weights on the WW2 gyrocompass were what induced precession. This is WRONG. The compensator weights are just as the name states, they are added to compensate for the weight imbalance to ensure the gyro assembly is perfectly balanced by weight. This gyrocompass used mercury tubes as well to induce precession.
