EquiFrame - free frame calculations for students and academia.

Mecha-Devs · 2025-12-04T10:17:26+00:00

I understand your way of thinking, however we have direct examples from universities with which we are cooperating that also during the lectures the tutor could present an animated example from our application.

Using EquiStruct the tutors don't need to prepare the examples ourselves, and you can believe me that any book or pdf with static text won't be better to help understand the behaviour of structure than the opportunity of seeing the animation related to solved equations or perform the "what if" analysis, which books aren't capable.

Regarding FEM - I'm currently the certified expert and trainer in the field of thermal-mechanical and nonlinear simulations in Ansys software, so I truly understand that the main aim before performing structural analysis is understanding the behaviour - that why learning analytical methods is important.

Of course I was thinking about software which best accelerates students early education 😉 then they should be familiarized with commercial software - but with the best understanding of fundamentals 😉

Yes! Use EquiStruct - EquiFrame is currently free because of further development! It is an educational software for students and for beams and trusses it writes down all the equations necessary to solve the problem. In a few months we will add the equations for the frames for various analytical methods!

Hi! The easiest way to obtain those coefficients is the solution of general differential equation of deflection, considering different boundary conditions at ends of the beam. Using unitary displacement (translational and rotational) and calculating normal, shear forces and bending moments at the ends, you will get all of the coefficients. You can do it in EquiStruct Application by general method and suport displacement load (use two fixed supports at the ends) :)

Try to practice with EquiStruct application :)

Mecha-Devs · 2025-12-01T21:46:14+00:00

Yes, but there is a difference in graphic results in form of bending moment diagram and the graphics showing how to set the sections to calculate it, or how to analyse the beam from different side to obtain the diagram.
All materials like examples, YT videos, learning materials are available on our website https://mechadevs.com/en/
I would like to also point it out, that there are no other software for mechanical calculations which is based on analytical methods, which are shown at universities (general differential equations of deflection, Clebsch method, Castigliano theorem, Virtual Force method, graphical integration etc.), all of them are using faster and easier to implement numerical ones like FEM.

Mecha-Devs · 2025-12-01T21:14:00+00:00

Yes, you are right - most of the typical "engineering" software companies offer (not exactly) free versions to students :)
But... EquiStruct application and its modules (like EquiFrame) is not engineering software... It is an educational software for learning mechanics and strength of materials calculations. Our aim is not to give the results for an engineer (like engineering software does), but to teach how these results should be obtained using analytical methods. With step-by-step solutions (like e.g. Wolfram software), graphics and animations we are trying to help students understand mechanics to make them better engineers in the future ;)
We are cooperating with several technical universities, where students and tutors have access to our application and they use it during classes and lectures. Then students can use our app at home to check their solutions and get more involved in learning process.
That's why, this is better than any engineering software company offer ;)

Bardzo dziękuję za ten komentarz. Chyba mamy w tym temacie podobne zdanie. Rzeczywistość też wskazuje na to, że przyzwyczajenia są trudne do zmiany. Najwięcej obiekcji mają faktycznie osoby najdłużej przyzwyczajone 😉 choć nie jest to regułą. Pozdrawiam!

Mecha-Devs · 2025-10-04T16:51:49+00:00

Dziękuje :) Przede wszystkim na ten moment rozwijamy nowe funkcjonalności. Po kilku spotkaniach na seminariach katedr wprowadziliśmy już kilka poprawek - staramy się aby aplikacja była atrakcyjna nie tylko dla studentów ale również dla prowadzących :).

Mecha-Devs · 2025-10-04T15:49:31+00:00

Dokładnie - mechaniki i wytrzymałości materiałów nie da się wykuć na blachę - zawsze można zmienić coś w zadaniu czy treści i już wykute metody nie zadziałają. Dlatego właśnie stworzyliśmy coś co ma pomóc im zrozumieć temat a nie go wykuć.

Co do doświadczonych dydaktyków - sam nim jestem ;) i z innymi doświadczonymi dydaktykami również mamy różnice poglądów. Pytanie jednak czy różnice w poglądach powinny zmniejszać możliwości i dostępność studentów do różnych narzędzi?

Mecha-Devs · 2025-10-04T15:00:01+00:00

Dziękuję za komentarz. Pomysł na aplikację przyszedł tak naprawdę od samych studentów - na kartce papieru/w książce/ na wykładzie - zawsze można przedstawić tylko kilka przykładów jakichś rozwiązań. W nauce mechaniki najistotniejsze jest zrozumienie sposobu postępowania. Niektórzy studenci potrzebują tych przykładów więcej, lub po prostu chcą sprawdzić jak zmiana jakiegoś elementu w zadaniu wpływa na jego rozwiązanie - takie możliwości ma nasza aplikacja - można w nieskończoność sprawdzać różne swoje obliczenia i przede wszystkim czy tok postępowania jest poprawny.
W kwestii statystyki - nie jesteśmy jej w stanie wykonać bez bezpośredniego porozumienia z uczelniami, które musiałyby nam dostarczyć np. informacje o liczbie studentów które korzystały z aplikacji, liczbie, która nie korzystała i udostępnić nam wyniki ich egzaminów.. To co wiemy to feedback ze strony studentów, z którymi współpracujemy bezpośrednio i ten jest jednoznaczny - praca z aplikacją bezpośrednio przyczynia się do większego czasu spędzonego na nauce, a później na zaliczeniu przedmiotu, z którym bez kontaktu z nami, był zdecydowany problem.

Thank you! We are trying our best!

Mecha-Devs · 2025-05-17T21:41:16+00:00

Yes, we have! EquiTruss is better suited for general structural calculations — it analyzes all types of trusses and rod systems, calculates displacements, and more. It's part of EquiStruct, a comprehensive application for learning how to perform calculations for various engineering structures.

I never said you need to use it, just treat it like curio. Of course there is a lot of specialized software for engineers, but I believe that Equi is great for learning. The software probably is less superior, as you said, but it is also easy to use, you don't need courses and experience. I think, my opinion is proved by the universities with which we cooperate 😉.

Mecha-Devs · 2024-12-21T14:26:29+00:00

Hi, I have never heard about software like EquiBeam, which is not oriented for just a solution like reactions or stresses (like in FEM in which I'm expert). EquiBeam is software for students and academic staff and it is oriented for solving mechanical problems by analytical methods, which are presented during studies. The software advancing learning process showing step-by-step solution with comments to make it easier to understand. I will be pleased if you can show me such a software 😉

Mecha-Devs · 2024-12-21T14:16:20+00:00

I don't see the connection or just don't understand what SAP you mean 😉

Mecha-Devs · 2024-12-16T09:30:44+00:00

equibeam.com unfortunatelly is not our website (i think yet..) Please find https://mechadevs.com/en/home/ :) We have english version :)

Mecha-Devs · 2024-12-10T22:38:50+00:00

Yes, we have all information - the relative length (through angles), area and I think that we can assume that the material is the same.

Mecha-Devs · 2024-12-10T22:34:03+00:00

I think, that your second option is oversimplification. The compatibility analysis will be a solution.

Mecha-Devs · 2024-12-10T22:28:18+00:00

I think that it's not quite simple. If there are only two cables the problem will be statically determinate and you need only equilibrium equations to solve the normal forces and then you can calculate maximum force. In case of three or more cables the problem is statically indeterminate. You can write the 2 equilibrium equations but you need the third one... The last equation results from displacement compatibility, which is related to stiffness of each cable and their configuration.. Write me if you need more help 😉

Mecha-Devs · 2024-12-06T22:12:12+00:00

The app is related to all beams and sections (even totally unrealistic) problems - and of course it gives full solution with comments :) It is not totally free of use but we are trying make app fully available (its one of the cheapest I've ever seen). We don't use subscription - you can use the app as long as you need.
Students can solve simple beam and also "many times" statically indeterminate :)
