The conception of force is, so to speak, eliminated from the conditions of the problem, which is reduced to one of pure kinematics.
It reviews the principles of statics and kinematics and applying them to the approximate analysis of pin and rigid jointed frames.
Thirteen design requirements, including kinematics, kinetics, and stability aspects, are described.
The mere geometrical description and analysis of various types of motion, apart from the consideration of the forces concerned, belongs tt kinematics.
Michelson's group developed a loaded, unconstrained model in which to study the kinematics of ankles which were destabilized in various ways.
