This talk will review the common methods of obtaining equations for the analysis and design of systems of rigid bodies which have relative motions. The algebraic and the essential sine-cosine character of such equations is pointed out. Once this is established, the main body of the talk will deal with the solution of sets of such equations. Emphasis will be placed on elimination methods, and especially on methods of obtaining auxiliary equations from the original set.
This talk will review what we have learned in the last several years by the use of elimination methods. It will be pointed out that classical techniques of elimination usually are too cumbersome, but with slight modifications the same basic concepts can lead to effective algorithms.
