Document Summary

Biomechanics application of physics to the understanding of the motions and deformations of body segments, organs, structures, tissues, cells, due to forces, pressures, torques, shears, etc. Body is made up of rigid segments. Each end has a joint that links rigid segments. Assumption made that isn"t entirely correct (we have muscles and fat which help move) The mathematical model used is the same for humans and for robots. The more segments you define the more accurate, and the more math it requires. Can attach sensors to segments and measure how you move (i. e. accelerometers) From joint to joint it does not move or flex. Joints have a well defined number of degrees of freedom". When you have 2 bodies in 3d there are 6 degrees of freedom. If you are going to attach them you must get rid of at least 1 degree of freedom. Bones, ligaments, etc. can constrict degrees of freedom.
