Why does the period of precession of a gyroscope have to be way larger than it's spin period so that it's motion can be modelled?
Mathematically, torque induced gyroscopic precession may be modelled with the following equation:
$$
{\displaystyle T_{\mathrm {p} }={\frac {4\pi ^{2}I_{\mathrm {s} }}{\ mgrT_{\mathrm {s} }}}={\frac {...

Gyroscopic Effect at non-90 degree offsets
So I’m well aware of the way that the gyroscopic effect is normally described, that a torque applied to a rotating object will take effect 90 degrees later on the rotation (forgive me if I’m misusing ...

Is it possible to find the position of spherical ball only using gyroscope raw data?
Assuming the spherical ball undergoes pure rolling and errors from gyroscope can neglected. Can I use angular velocity from gyroscope to find the position by computing rotations times its radius?

Why are the body axes of an axisymmetric body principal axes of inertia?
I am reading "Vector Mechanics for Engineers, Statics | Dynamics", 12th edition, by Beer, Johnston, Mazurek, Cornwell, Self.
In section 18.3C Motion of an Axisymmetric Body Under No Force, the ...

Angular Velocity of a point on a deflated tire (gyroscope measurement)
Before I do the experiment, I am a bit confused about the expected signals provided by a 3-axis gyroscope (angular velocities vs. time) mounted on the edge of a (slightly) deflated car tire when the ...

How can I obtain $x$ and $y$ rotation of an object in its reference frame when it is rotated/measured from another frame of reference?
I am working with the gyroscope on a mobile device. The goal is to get the x and y rotation of my phone from its reference frame no matter the direction I am pointed in real-life along the z-axis in ...

Is flipping a coin is a stable rotation?
If I rotate a coin with dimensions: 10X10X1
about 1 of the big axes(10) in space, where there is no torque, will the rotation will be stable just like a frisbee or a football regular rotations are? ...

Impulse on a Gyroscope
I've been studying gyroscopes, and I understand why a fast spinning gyroscope doesn't fall. However, I don't understand why a slow spinning gyroscope does fall, or why a large enough impulse to a fast ...

Gyroscopic precession on a friction-less surface
I am having trouble understanding the total energy for a heavy spinning symmetric top (Gyroscope) on a friction-less surface.
I am trying to understand it via the Lagrangian of the gyroscope. My ...

Gyroscope precession torque
We're probably all familiar with the demonstration of gyroscopic precession where a man sits on a swivel chair holding a bicycle wheel (like this: https://www.youtube.com/watch?v=1fWl2LNpcak).
And ...

Why does Uranus not experience gyroscopic effect?
As I understand, gyroscopic effect is when a body has multiple distinct axes of rotation. This video shows this effect when a body already rotating in one axis is made to rotate another axis ...

Motor-powered gyroscope's precession speed
I was doing experiment about the gyroscope's precession speed and I made my own gyroscope, which is the one in the picture. It is the motor-powered gyroscope as I found out the one made with bearing ...

Best learning of gyroscopic motion? [duplicate]
I crave to learn the nitty-gritty of attitude dynamics - namely I want to get really up close and personal with angular momentum, gyroscopic motion, non-inertial effects. I'm looking for a resource ...
