Parallel Axis Theorem

Transfer of Axis Theorem


For Area Moments of Inertia


: is the crosssectional area.
: is the perpendicuar distance between the centroidal axis and the parallel axis.


For Area Radius of Gyration


: is the Radius of Gyration about an axis Parallel to the Centroidal axis.
: is the Radius of Gyration about the Centroidal axis.
: is the perpendicuar distance between the centroidal axis and the parallel axis.


For Mass Moments of Inertia


: is the mass of the body.
: is the perpendicuar distance between the centroidal axis and the parallel axis.


For Mass Radius of Gyration


: is the Radius of Gyration about an axis Parallel to the Centroidal axis.
: is the Radius of Gyration about the Centroidal axis.
: is the perpendicuar distance between the centroidal axis and the parallel axis.
