Perpendicular : Moment of Inertia (Perpendicular Axis Theorem) Calculator

Posted by Dinesh on

Calculate perpendicular moment of inertia by using simple perpendicular axis theorem / formula calculator online.

In physics, the perpendicular axis theorem (or plane figure theorem) can be used to determine the moment of inertia of a rigid object that lies entirely within a plane, about an axis perpendicular to the plane, given the moments of inertia of the object about two perpendicular axes lying within the plane. The axes must all pass through a single point in the plane.

Define perpendicular axes x, y, and z (which meet at origin O) so that the body lies in the xy plane, and the z axis is perpendicular to the plane of the body.

Formula:

Iz = Ix + Iy

where,
Ix = Moment of inertia (x axis)
Iy = Moment of inertia (y axis)
Iz = Moment of inertia (Perpendicular axis)
