Deflection is a powerful, versatile calculator for beams, 2D trusses, and 2D frames. The interface is simple and intuitive, and the graphical output is state-of-the-art. In addition to reaction, shear, bending moment, and deflection results, Deflection also computes internal shear and bending stress along the cross section and along the beam. 2D FRAME AND TRUSS EDITOR The 2D editor is seamlessly integrated with the beam editor. Draw arbitrary frame and truss structures and apply loads and constraints using the same simple interface as for beams. You can visualize results directly within the 2D editor, or you can select a beam and get additional insights. INTERNAL STRESSES Obtain internal bending and shear stress diagrams in addition to shear, bending, and deflection diagrams. The internal stresses can be visualized along the length of the beam as well as along the vertical axis of the cross section using the beam editor. CROSS SECTION EDITOR Edit built-in cross sections. Moment of inertia and area values are automatically calculated and applied to the rest of the beam calculations. MORE FEATURES • The built-in database contains more data for your reference and convenience. • Apply beam self-weight optionally • Unlimited design files • Quick-start templates CONTACT We like to hear from you!

ACORD Mobile is designed for a broad audience; civil engineers, carpenters, technicians, architects, and engineer students alike. ◆ Are you a professional? You often have to provide a section estimate on short notice on-site or at a customer meeting. With ACORD Mobile on your phone, you now have an application that allows you to calculate and optimize your wood or steel beams effortlessly and precisely, wherever you are. ◆ Are you a student? Go effortlessly from theory to practice. Look at diagrams of bending moment, shear, or deflection. Learn the intricacies of Eurocode 3 (steel) and 5 (wood) in a fun and enjoyable way. Download ACORD Mobile and you’ll be able to: • Analyze the static behavior of your element on multiple supports and under any loads • Design floor and roof beams following Eurocode 3 (steel) and 5 (wood) standards • Define your geometry with ease: Multiple spans, boundary conditions, slope, etc. • Define multiple loads in different categories as you please, or use our tools to guide you: -Permanent loads: With the help of our libraries, you can choose to apply predefined floors or roofs and even create your own and save them. Apply self-weight automatically if needed. -Live loads: Choose the category of loaded areas and the usages that apply to your case to apply the characteristic values defined by the European guidelines. -Snow loads: Define your country, zone, and altitude using our tool and maps to aid you. The corresponding snow load will be calculated automatically, considering the slope and the related National Annex. • Perform your analysis and design your beam in a quick and straightforward way: Make the right decisions for your material category and section dimensions using our optimization tool. Verify all relevant displacement and resistance criteria depending on your material and charges. Automatically calculate all Eurocode linear combinations. • See your results in detail: The educational presentation of the detailed equations explains the path and the intermediate calculations leading to the verification results. It allows you to understand in-depth the structural analysis carried out. You get graphs of each Eurocode criterion for each linear combination as well as an envelope. You also get nicely presented interactive diagrams for bending moment (M), shearing force (V), normal force (N), stress (S), displacements(w), rotation(θ), and reactions (R). • Change your analysis parameters and details. • Use the units of your choosing. • Save your studies for later use. *About Pro plan billing* Some of the above features are only available with ACORD Mobile Pro!

Verdict

The call

The clearest difference is price: ACORD Mobile at Free against Deflection's $4.99. ACORD Mobile also leads on rating (5.0 vs 4.6) and update cadence (every 11 days vs every 6 weeks). Deflection's advantage is in-app purchases (none vs 2) and ratings volume (115 vs 1). On ads, device support and iOS requirement there is nothing between them.
