What is the Parallel Axis Theorem? The parallel axis theorem can be used to determine the moment of inertia of a rigid body around any axis. Oftentimes the moment of intertia of a rigid body is not taken around the centroid, rather some arbitrary point. A good example of this is an I-Beam.

Parallel Axis Theorem The moment of inertia of any object about an axis through its center of mass is the minimum moment of inertia for an axis in that direction in space. The moment of inertia about any axis parallel to that axis through the center of mass is given by

Parallel Axis Theorem • The moment of area of an object about any axis parallel to the centroidal axis is the sum of MI about its centroidal axis and the prodcut of area with the square of distance of from the reference axis. • Essentially, I XX = I G +Ad2 • A is the cross-sectional area. d is the perpendicuar distance between

This theorem is also known as Huygens- Steiner theorem. Using this theorem, one can calculate the moment of inertia of a rigid body in any axis, it is given that the sum of its moment of inertia about parallel axis through its center of mass and the perpendicular distance between the two axes.
