Free Body Diagram Ruler - 6in This may be helpful for first-year physics students. After using it in class for a few weeks, the most frequently used feature has been the various size boxes. I was able to create cleaner diagrams in class by using this tool instead of drawing freehand. *** Hopefully soon, I plan to add a compass section for drawing arcs (pendulums and circular motion problems). It will utilize your finger as the center of the compass (center of the circle). The holes will be spaced at different diameter intervals. *** Additionally, I am working on improving line segments. They are currently too narrow for a standard mechanical pencil.
