I think I understand the rank one and rank two systems, but I’m not clear about what the 3rd represents on a Cartesian plane.
My mental model involves tying concepts to CAD design and assemblies. I am coming from FreeCAD where picking origins and designing everything on planes is critical.
The thing that I really don’t understand about tensors yet is how the origins are derived and relate with different objects in 3d space. I want to assume R3 relates to the origin but I am not sure.
Already discovered. That’s when I knew I had no chance of grasping this as an intuitive concept.
