How does the principal axis relate to Fermat's principle of least time?

In RAM Elements, analysis and design results are referenced to a local axis system (1, 2, 3) or a principal axis system (1', 2', 3').

Description. Stop if addition of 0.1 * sigma in a principal axis direction does not change mean value. The principal axis of jets — an attempt to analyse high-energy collisions as two-body processes · References · Cited by (0) · Recommended articles. Dec 11, 2013 ... This way you get the value of t hence the equation of principal axes and value of a and b come to be positive , hence it is an ellipse . May 3, 2019 ... The calculations suggest a triaxial shape of the nucleus at high spins, and the band may represent rotation of the nucleus about the longest axis.
