comment Component perpendicularity
Can you please state this as a question? Right now it is a statement; I presume you wish to know whether it is true or how to prove it?

comment Extracting angular velocity tensor from orthogonal matrices
@linello How did you obtain the formula for $\omega$ in your comment above (sept7'11)? I am trying to solve the equation for $\mathbf{x}$ in $\mathbf{Y}$ but cannot reach your solution.

comment Extracting angular velocity tensor from orthogonal matrices
@joriki When solving $\mathbf{Yx=x}$, how do we know that we obtain the correct direction $\mathbf{u}$ and not the opposite direction $-\mathbf{u}$?

comment composition of rotation matrices
@Muphrid I have modified the question to indicate the order of the angles and emphasize that there is no intended conversion between extrinsic and intrinsic rotations.

@Rahul I have modified the question to reflect that the rotation is to be applied to the left on column vectors.

revised Given a set of rotation matrices, is it possible to determine the rotation conventions employed?
The question has been stated more clearly in the title and in the body of the text. The matrices therein have been written in standard MathJax, converted from pasted Mathematica Code (this is not a Mathematica-related question). The conventions have been rewritten more conventionally.
