In statics and stability analysis, this describes a system that finds a new resting state wherever it is moved. A perfect sphere resting on a perfectly flat, level surface exhibits this exact state. Engineers encounter this when designing rotating assemblies where the center of mass aligns exactly with the axis of rotation, preventing any tendency to self-right or flip.
