Parallel Axis Theorem

Parallel Axis Theorem

Area Moment of Inertia | Radius of Gyration

For Area Moments of Inertia

: the cross-sectional area.

: the perpendicuar distance between the centroidal axis and the parallel axis.

For Area Radius of Gyration

: the Radius of Gyration about an axis Parallel to the Centroidal axis.

: the Radius of Gyration about the Centroidal axis.

: the perpendicuar distance between the centroidal axis and the parallel axis.

For Mass Moments of Inertia

: the mass of the body.

: the perpendicuar distance between the centroidal axis and the parallel axis.

For Mass Radius of Gyration

: the Radius of Gyration about an axis Parallel to the Centroidal axis.

: the Radius of Gyration about the Centroidal axis.

: the perpendicuar distance between the centroidal axis and the parallel axis.
