Rectangular beams however offer a simple formula for determining their moments of inertia. Since we have split it into three rectangular parts we must calculate the moment of inertia of each of these sections. The moment of inertia second moment or area is used in beam theory to describe the rigidity of a beam against flexure see beam bending theory.

Calculate an i beam s second moment of inertia by dividing it into sections and calculating each one s inertia. Iy x2 da 2 where. Given here is the steel i beam moment of inertia formula to calculate the steel i beam area moment of inertia polar moment of inertia based on the required values.

It is widely known that the moment of inertia equation of a rectangle about its centroid axis is simply. It is calculated by taking the summation of all areas multiplied by its distance from a particular axis area by distance. Polar moment of inertia is a measure of a circular beam s ability to resist torsion.
