The Challenge of Learning Structural Engineering
Remember staring at static textbook diagrams, wondering how those perfect arrows and neat calculations related to real structures? Traditional teaching methods can't show students what they really need to understand: how forces actually flow through a beam, or why adding one more support suddenly makes a problem unsolvable.
BeamLab bridges this gap by turning abstract concepts into hands-on exploration.
You can play around adding all kinds of forces to a beam. This makes you realize the direct effects on the beam.

Technical Implementation
Built with Python and Pygame, BeamLab implements rigorous structural analysis using the method of sections to compute internal forces N(x), Q(x), and M(x). The tool features optimized rendering, event-driven architecture, and proper unit conversions between display coordinates and engineering units.
Sometimes the best way to understand complex systems is to play with them. BeamLab proves that serious engineering education can be seriously fun. That's why I created BeamLab. I wanted to give students what I wish I'd had: a way to play with structural concepts.
