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. |
