On the Special Bases of Two- and Three-Screw Systems (ASME 1993)

The geometries of screw systems are well-defined in some special bases such as inthe principal coordinate systems. However, it is not easy to construct the principalcoordinate system of a screw system from a given set of screws. Methods of findingthe special bases of two- and three-systems by means of linear algebra are presented.Geometric characteristics and their d..
