In this episode, we continue our exploration of aligned trios, but we move beyond purely horizontal alignments. Last time, horizontal configurations helped us reveal key aspects of the link between geometry and mechanics. Now we extend the idea to more general orientations. When quantities align along any direction, they still generate three parallel lines in the kinematic plane — now diagonal, reflecting the slope in the mechanical plane. As before, their ordering is controlled by a single dimensionless parameter that depends only on the mechanical quantities: the index. If the index is greater or less than one, the trio falls into two qualitatively distinct regimes. Every trio is dual, and today we clarify what this duality means in practice.
