Beam Deflection Calculator

Blue Ketchep
Solve beam deflection problems easily and obtain results, graphs, and equations to double-check your work!

This is a great learning tool for mechanical engineering, civil engineering, and architecture students. It is an excellent companion for engineering statics and mechanics of materials college-level courses. While you should not rely on this tool for professional engineering design, you may still find it useful to double-check your hand calculations and results.


Quickly place loads and supports along the beam using a powerful interactive graphical design. Our solver algorithm will automatically handle individual sections and superposition of loads.

Immediately see how the beam bends in response to the applied conditions. The shear, moment, slope, and deflection diagrams and equations update automatically.


Each type of load and support has a different icon. You can simply drag any of them onto the beam.

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


Either specify moment of inertia and elastic modulus values directly, or find common shapes and materials using the built-in databases.

• Steel: American and European shapes
• Lumber: American shapes
• Other materials can be used used with custom shapes.


Easily edit and rotate cross sections if the built-in dimensions do not quite match your use case. The beam properties are automatically recomputed and used by the beam deflection solver.


• Metric and standard measurement units
• Smart diagrams automatically detect local maxima and minima and zero-crossings.
• Your work is automatically saved in separate files so you can return to it in the future.
• Quick-start templates help you to start right away!

What's new in version 5.3.0
This release introduces the ability to compute and apply beam weight automatically as well as numerous improvements throughout the app, including performance and stability fixes.

• NEW: The checkbox next to the material density value allows you to apply beam weight as a load. Modifying the material density or cross section area values automatically enables this checkbox, but you can still uncheck it to disable it.

• NEW: When you explore sections in the built-in database, you can now see additonal reference values that you may find useful. Any rows with a light gray background are interactive. If you tap on them, they will be highlighted for visualization in the diagram on top of the screen.

• NEW: The app now enforces a minimum beam length based on 10 times the height of the cross section, if one is specified. Changing the height of the cross section will automatically cause the beam length to increase if it is less than this threshold.

• IMPROVED: You may notice that the beam visualization now reflects the proportional size of the cross section.

• IMPROVED: When a cross section is not specified, instead of rendering a default shape, we now simply draw a line that represents an abstract beam. Even when a cross section is specified, we now render a thin center line, which makes the deflection of the beam easier to follow visually.

• CHANGED: In order to make room for the new options needed to enable the new beam weight feature, you will notice a change in layout and interaction in the material and cross section widgets.

• CHANGED: Previously, when you changed the default app unit settings, any values entered for the current file would get overwritten using the new units. This behavior does not make sense now that there are multiple files, so we disabled it. Now, when you change the default app unit settings, only the output calculation values and the default values for new beams and loads are affected.

• CHANGED: When using English (Standard) units, the scroller in the numpad view changes your value in increments that are fractions of 2 (example: 0.25", 0.125", etc). We hope this makes it easier to work with common values in these unit types. Let us know!

• FIXED: We improved stability in some phones where the app may have sometimes crashed due to memory usage. We also improved performance in most phones where loading and searching the beam library may have been slow or laggy.
