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 mechanics courses often fail at teaching students an intuition for basic stuff: How do forces act on a beam? What happens if you change the position of a load or add another one? Or why is adding one more support making a problem unsolvable?
BeamLab tries to bridge this gap by turning abstract concepts into hands-on exploration.
You can play around applying all kinds of forces to a beam. The program will output you the distribution graphs immediately. This helps you understand the direct effects of loads.

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.
