    Angles Euler
AI Thread Summary
Tait-Bryan angles and Euler angles differ primarily in their axis rotation definitions, with Tait-Bryan angles representing distinct yaw, pitch, and roll rotations, while Euler angles involve the same axis for the first and third rotations. The discussion highlights that Euler angles are often favored in mechanical engineering, whereas Tait-Bryan angles are more commonly used in marine and aerospace applications. Concerns about gimbal lock, which affects Euler angles by losing a degree of freedom during certain rotations, are noted, although there is debate about whether Tait-Bryan angles are entirely free from this issue. The conversation also touches on the terminology used in describing rotational motion, questioning why "steady precession" is more commonly referenced than "steady yaw." Overall, the choice between the two systems may depend on specific applications and the nature of the rotational problems being addressed.

TL;DR Summary
Which to use; and in which problems: Tait or Euler angles?
Good Morning!

I understand that the definitions and notations used for Tait–Bryan angles are similar to those described above for proper Euler angles, and I can work problems in either. However, I lack the ability to "rise above both" and categorize them.

I do understand that the only difference is that Tait–Bryan angles represent rotations about three distinct axes (yaw, pitch, roll) , while Euler angles use the same axis for both the first and third elemental rotations (precession, nutation spin).

That said, it SEEMS to me that Euler angles are preferred in mechanical engineering
Tait are preferred in marine and aerospace

Is there any reason (or any special problems) such that one is better than the other? Or does it really not matter?

And while I am at it: why do we talk about "steady PRECESSION" and never "steady YAW"

Here's a video description of the various rotations, although watching it may give you vertigo.

and here's a cheat sheet comparison of the types of rotations:

I did see some references that said Tait-Bryant angles were more suited to particle motion. It seemed the Euler angles suffer from gimbal lock in certain rotation combos, losing one degree of freedom, whereas Tait-Bryant angles don't have this issue.

Vaguely I recall using Frenet-Serret formulas to set up a coordinate system relative to the particle traveling along a trajectory using a tangent vector, normal vector, and their cross-product to define axes relative to the object.

Perhaps @Mark44 or @fresh_42 can explain this better.

I think that Tait-Bryant still has gimbal lock problems. Your first linked reference indicates a gimble lock problem.

IMO, if the gimble lock problem could be avoided by using Tait-Bryant instead of quaternions, then quaternions would not be used nearly as much.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
