Cross Section Calculator

Cross section calculator: area, inertia, modulus, neutral axis

Cross Section Calc is a free cross section calculator that quickly computes section properties.
By entering dimensions, you can instantly calculate section area, second moment of area (moment of inertia), section modulus, and neutral axis position.

The app provides a simple and intuitive workflow for both learning and practical design checks.
It is lightweight, fast, and fully usable offline.
