11+ Calculating Section Modulus. Where i = moment of inertia, y = distance from centroid to top or bottom edge of the rectangle. In this blog post, we’ll cover section modulus formulas for different shapes, so you can calculate it more quickly.

The elastic section modulus (s). In this blog post, we’ll cover section modulus formulas for different shapes, so you can calculate it more quickly. Equations for the section moduli of common shapes are given below.
