KINEMA TIC SYNTHESIS.
. Diagram of the Synthetic Processes. The importance of this part of the subject is so great that I have thought it worth while to add the accompanying diagram (Fig. 362) in the hope that it may make the connection between the different synthetic methods somewhat more clear to the reader. Kinematic synthesis as a whole divides itself into direct and indirect, and each of these classes again subdivides into general and Pairs of elements Knovjn pairs of elements. Known Kinematic chains FIG. 362. special. The direct synthesis should combine the kinematic elements at its command into the required pairs or chains according to the laws of pair- or chain-formation. In part it strikes upon insoluble difficulties, in part it furnishes results which have no practical value. The indirect synthesis first (as special M M 2
