Deflection is the most interactive, fast, and precise app available for structural beam analysis. Design visually and obtain engineering results, graphs, and equations instantaneously!

Simply place loads and supports on the beam, and see how it bends. Find a cross section in the built-in library, or define a custom shape. Deflection, internal stresses, and other useful results are automatically updated.

This software is the result of over six years of continuous development and innovation aimed at mechanical engineering, civil engineering, and structural engineering. This tool will help you apply beam elastic theory from day 1 as you are learning Mechanics of Materials, and it will be your go-to pocket reference any time in the future.

Obtain design results and diagrams in real-time.

Specify values directly, or find common shapes and materials using the built-in databases.

Edit built-in cross sections. Shape properties are automatically calculated.

Simply drag any load or support on the beam.
