Kraftpunkt

Kraftpunkt is a German term that combines Kraft (force) and Punkt (point). In technical contexts it is used to denote the location at which a force is applied to a body. The Kraftpunkt, together with the line of action of the force, determines the moment or torque produced about a pivot or reference point.

In mechanics, the concept of the Kraftpunkt is relevant for static and dynamic analyses. The moment generated by a force depends on the distance from the pivot to the Kraftpunkt, i.e., the lever arm. Precise use of the term can vary by discipline, and some authors prefer more explicit expressions such as “point of application of the force” or “line of action.”

The Kraftpunkt should be distinguished from related concepts such as the center of mass or the centroid, which relate to inertia and mass distribution rather than the point where a force acts. In biomechanics and structural engineering, the Kraftpunkt is sometimes employed when modeling forces on joints, members, or contact surfaces, though terminology differs across fields.

In non-technical or everyday German, the term may appear less frequently, and other phrases like “Angriffspunkt der Kraft” or simply “Kraftpunkt der Kraft” might be used depending on context. In English-language texts, the standard phrasing is usually “point of application of the force” or “line of action.” Overall, Kraftpunkt is a field-specific term whose exact meaning depends on the disciplinary convention.
