Euler Angles/ Rigid Body application

Click For Summary

Homework Help Overview

The discussion revolves around a problem involving the application of Euler angles in a three-dimensional context, specifically related to the orientation of an artillery piece. The original poster describes a scenario where the piece is initially aimed at an azimuth of zero, and then experiences a tilt and elevation change, prompting a need to determine the new azimuth.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to understand how to calculate the new azimuth after applying tilt and elevation to the artillery piece. Some participants question the level of understanding of fundamental concepts such as reference frames and vectors, while others express uncertainty about how to assist given the original poster's self-identified lack of mathematical experience.

Discussion Status

The discussion is ongoing, with participants exploring the complexities of 3D rotation and the necessary foundational knowledge required to approach the problem. There is no explicit consensus, but some guidance regarding the importance of understanding reference frames and vectors has been suggested.

Contextual Notes

The original poster mentions a specific real-life application and provides details about the artillery piece's dimensions, which may influence the calculations but are not fully explored in the discussion.

I apologize upfront, as I have no experience with math to begin with. However, I have a real life problem I am trying to figure out here at work and I would appreciate some help. Here is my situation:

Homework Statement



In a 3 dimensional plane, I have an artillery piece pointing at azimuth zero. Then, if I tilt (bank or roll) 4 degrees to the right, it is still pointing at azimuth of zero.
However, if I raise the tube 65 degrees it no longer points at AZ of 0.
How do I determine the new azimuth with the elevation and tilt added? The total length is 3 meters long, if that makes a difference.

The Attempt at a Solution


I tried to break it down into trigonomic functions before I knew about Euler angles, but it really goes beyond my mathematical comprehension. Any help would be great.

Thanks in advance.

I am not sure what kind of help can be given here. You already know about Euler's angles.
 
Right, but like I said I have no idea what all the little squiggly shapes and symbols mean. My knowledge of Euler's angles does not extend past how to spell Euler...
 
Well, the whole topic of rotation in 3D has a lot of material and a number of different approaches. At a minimum, you have to understand, solidly, reference frames and vectors. Do you have that?
