    Euler Precession
AI Thread Summary
Euler angles and Tait-Bryan angles are two approaches to studying body rotations, with key differences in their axis representation. Tait-Bryan angles involve distinct rotations about three axes, while Euler angles use the same axis for the first and third rotations. In Euler angles, the concept of "Steady Precession" describes a scenario with constant precession and spin rates. The analogous case in Tait-Bryan angles is known as "Steady Turn," where the yaw rate is constant, pitch rate is zero, and roll rate is constant. This term is frequently applied in aviation and aerospace contexts.

TL;DR Summary
what is the analogue of steady precession when using the Tait -Bryan angles
Good Morning

When one studies body rotations, there are two general approaches one uses: Euler Angles vs. Tait-Bryan Angles.

The significant difference is that:
  • Tait–Bryan angles represent rotations about three distinct axes (e.g. x-y-z, or x-y′-z″): Yaw, Pitch, Roll
  • Euler angles use the same axis for both the first and third elemental rotations (e.g., z-x-z, or z-x′-z″): Precession, Nutation, Spin

With Euler angles, there is a special case of STEADY PRECESSION: precession rate is constant, nutation rate is 0, spin rate is constant.

Is there a NAME for the analogous case, when modeling with Tait? Yaw rate is constant, pitch rate is 0, roll rate is constant?

Yes, there is a name for the analogous case in Tait-Bryan angles. It's called "Steady Turn," also known as "Constant Turn" or "Banked Turn." In this case, the yaw rate is constant, the pitch rate is zero, and the roll rate is constant. The term "banked turn" refers to the fact that the vehicle or object is banked or tilted to one side, like an airplane during a turn. This term is commonly used in aviation and aerospace engineering.
 
Thread 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
