A tutorial on free body diagrams that includes situations involving gravitation, the normal force, friction, push/pull and tensions. Each situation has Free Body Diagram (FBD) sketches and a detailed analysis. There is also a three level graphic-based FBD self-testing quiz which is elaborate but a little slow.
