Homework Help: Euler Angles/ Rigid Body application

  1. Jun 10, 2013 #1
    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:

    1. The problem statement, all variables and given/known data

    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.

    3. 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?
