#### Area Moment of Inertia Section Properties of Square Calculator

This engineering calculator will determine the Area Moment of Inertia Section Properties and section modulus for the given cross-section. This engineering data is often used in the design of structural beams or structural flexural members. There are two types of section moduli, the elastic section modulus (S) and the plastic section modulus (Z).

See Area Moment of Inertia Section Properties Properties Menu for additional structural section properties equations and calculators.
