Moment of Inertia Calculation for Circular Section

This calculator computes the moments of inertia (Ix, Iy, Ipolar) of a circular section. You can enter the outer and inner radius values to obtain key characteristics — moments of inertia about horizontal and vertical axes, polar moment, area, and centroid coordinates. All this without complicated formulas or manual calculations. This calculator is suitable both for engineers performing structural analysis and for those who simply want to verify their ideas. It runs directly in the browser, requires no registration, and minimizes distractions. Just enter the parameters and focus on your task, not on technical details.
