Document Summary
Forms a local reference system that allows the identification of a point on the body relative to the body segement instead of relative to an external reference point. Describes planar motion and results in 4 quadrants in which movement occurs. 3 orthogonal axes b/c depth is added (z axis) Can be used to determine the horizontal and vertical rxn force s of the foot at the ankle during the swing phase of gait. 2d reference system where 2 axes are perpendicular to each other and form a vertical and horizontal plane. Forces that cause motion are determined by the resulting motion. Human body is a series of segments. Body is made up of frictionless joints. Each segment has a centre of mass at a fixed point. The moment of inertia about an axis of each segment remains constant. Assume that the 3 lines don"t change in length and that the markers form a triangle shape on the body segment.
