The International System of Units or SI unit of the moment of inertia is 1 kilogram per meter-squared Accurately and quickly calculate the moment of inertia, Schwerpunkt, torsion constant and statical moment of area of a beam section using Sk圜iv's Section Builder 's Moment of Inertia Calculator is an online physics tool to measure the rotational inertia of different objects of most common shapes based on the mass distribution and their axis, in both US customary & metric (SI) units. The calculation for the moment of inertia tells you how much force you need to speed up, slow down or even stop the rotation of a given object. Values are provided for both positive and negative bending, where positive bending is defined as the top-most or left-most portion of the cross-section being in compression. Elastic Section Moduli: The elastic section moduli are equal to the second moments of area / moments of inertia divided by the distance to the farthest fibre in the cross-section perpendicular to the axis of bending. The Product Moment of Inertia is, by definition, zero for principal axes. Video: Free Moment of Inertia Calculator (Second Moment of Area
