Six Geometries in Macro Models | Essential Biomechanics 

This video can contribute to your learning curve about an essential topic: THE SIX GEOMETRIES. I use to say to my students: "First you study, then you see, you feel, you understand, you believe, you apply, and finally you consolidate this knowledge".
I hope this video can help you with these first steps. Tip: you only need a piece of electrical wire to train this exercise. The bracket models can be replaced by drawings. Try it! This proprioception will help you in understanding more complex appliances.
