tungsmechanik
Tungsmechanik is a term used in some theoretical discussions of mechanics to describe the study of systems whose inertia and constraint structure can change over time due to internal degrees of freedom or external fields. It emphasizes how coupling between slow, observable motion and fast, internal dynamics shapes overall behavior, leading to modified equations of motion and emergent forces.
The core idea is to model a system with external coordinates q describing the visible motion and
History and usage: The term appears in a limited number of texts within theoretical and applied mechanics
Applications: In engineering, tungsmechanik informs design of multibody systems with deformable components, vibration control, and energy
