Thanks for the reply. I've just looked through that section, and it seem that
omega x v (eq. 1.5-13) is a recurring theme in dynamics modelling. After doing unit analysis, I found that it gives acceleration. So I guess I will try making use of it in my own equations of motion. Another thing that caught my attention: equation (A) on page 70 seems very similar to the infinitesimal rotational transformation, although it has zeros in the diagonal instead of ones. The document doesn't explain how it is derived, but am I correct to say this is how it is done? eq(A) dt = [1, -d psi, d theta; d psi, 1, -d phi; -d theta, d psi, 1][phi; theta; psi] - [1, 0, 0; 0 1 0; 0 0 1][phi; theta; psi] Ampere On September 24, 2008 11:14:07 pm Jon S.
