Analyze structural beams quickly. Design visually and obtain engineering results, graphs, and equations seamlessly.

Whether you are in mechanical, civil, or structural engineering, unleash the full extent of practical Mechanics of Materials tools from day 1 as you are learning them, or come back and reference them any time in the future.

Simply place loads and supports on the beam, and select or customize any shape from the built-in library. Immediately see how the beam bends in response to the applied conditions. Deflection, internal stresses, and other results are automatically updated.


Obtain design results and diagrams in real-time.

• Shear
• Bending
• Deflection
• Internal bending stress
• Internal shear stress


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

• United States (steel and lumber)
• Europe (steel)
• Great Britain (steel)
• Canada (steel)
• Australia (steel and aluminum)


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

• Moment of inertia
• Area


Simply drag any load or support on the beam.

• Concentrated point loads
• Distributed loads
• Moment loads
• Simple supports
• Fixed supports
• Fixed hinges
• Floating Gerber hinges


• Apply beam self-weight optionally
• Automatic detection of local maxima and minima in diagrams
• Unlimited design files
• Quick-start templates
• Metric and standard measurement units

What’s New

Version 5.7.0

• NEW: Customize how cross sections in the library are sorted. Tap on the column headers to sort by cross section width, height, area, or moment of inertia (about strong axis).
• NEW: Choose to display either cross sectional area or moment of inertia (strong axis) in the cross section library. Tap on the drop down button on the right of the screen to configure which of these columns to use.
• NEW: Added some data for Japanese, Russian, and Indian steel cross sections.
• IMPROVED: Enabled additional properties for GB and CA cross sections.
• IMPROVED: Better search functionality. Now you can search by database (eg, "US", "EU", etc) or by material (eg, "steel", "lumber", or "aluminum") as well as by section designations (including alternative names).
• IMPROVED: Added translations of cross section property descriptions for many languages.
• FIXED: Minor rendering issues in iOS 13.

Nice beam calculator

I have really enjoyed using this very nice beam calculator. I've tried several and this is, by far, the most elegant interface. I love the presentation of the diagrams and how quickly you can modify the situations.
One constructive comment would be to add an option to use a custom rectangular shape. The material library includes concrete but you have to use a custom moment of inertia. Granted that's a super easy calc but it would be nice to stay in the app and just tap a length and width.
Love it, Love it though.

Needs polishing

Kinda klunky interface. The calculator layout is poor. Calculator needs means of entering scientific notation. Missing aluminum extrusions. Should have a way to favorite beam shapes and add user defined ones. I prefer scientific notation normalized to be x.xx x10^x not xxx.x x10^x

Not sure why 10x length limitation.

Developer Response ,

Thank you very much for your detailed feedback and requests! We always have to make a tradeoff between polishing existing features and rolling out new ones, but over time we try to address all sharp corners, so thanks for pointing some of them out!

Regarding the 10X requirement: The equations that the app uses internally assume that the beam is "slender", meaning that the length-to-height ratio should be greater than 10. If you need to design for something shorter, you may need to use a different type of analysis tool. You can find a mention of this in the general Wikipedia article on Beam Deflection
