This project includes some cool beam configurations! I intend to use these when my engineering class discusses moment of inertia, center of mass, trusses, planks, and deflection. I was already looking at the lesson plan for bridge building, but was so excited to find these beams in the files as well!
I will have my students use CAD to design their own beams and predict deflection after they've run some experiments with the ones that have been provided in this project. Thanks!
These did print with a bit of a curl to them, I wonder if they would print better if they were thicker.
