斯坦纳（Steiner）定理 (n)

Steinerische Satz (m)

parallel-axis theorem (n)

The parallel-axis theorem (Steiner's theorem) is used to transform area moments of inertia onto an axis running parallel to the centroid (gravity) axis.

In the case of components comprising composite cross-sectional areas, the parallel-axis theorem can be used to determine the area moments of the total cross-sections.

However, the parallel-axis theorem states that offset moment is not produced when a force is moved along its line of action, because forces are sliding vectors.
