🎬the stress tensor acts as a linear map that transforms the surface normal vector into the force vect

The stress tensor is a powerful mathematical tool that acts as a linear operator, linking a surface's orientation to the force acting on it. The demo visually demonstrates that the force vector is not a fixed quantity; its direction and magnitude are entirely dependent on the orientation of the surface, as defined by the stress tensor. This consistent, predictable relationship is precisely what defines a tensor.
