Kinematical analysis of two-parameter motions

In t hi 3 study, one- parameter, Bt and two- parameter B|| motions and their ki ne mati cs p r o pe r ti es a re i nvesti gated i n detai 1 s. In the first section, bacis concepts and some which explaines the subjects teorems well are given. In the second section, F'faff- forms are taken as a differential forms and exterior derivatives are defined related with the exterior product. In the third section, pole points and their pole curves, a line which is defined g in moving plane E and a line which is defined g" in constant plane E' are obtained. In fourth part the pole axes of two- parameter motions the density-inveriant of the mapping of the pole axes, the mapping of the pole axes, and mapping the of which pole axes density is zero are investigated and some teorems are given. In the fifth part, the points which draw a curve element are investigated and the constant -invariant conditions in E and E'- planes of a X point are given. In the sixth part, the fundamental motion Bj i n two- parameter motions B||, the norrned relative systems of it and the form of the a Pfaff- forms whether it is lineeri y dependent or independent and the exterior derivatives related with this manner are given. In seventh part, special B( -motions in B|| -motions are investigeted. In the last part the references are given.
