Analytical Geometry in Common Layouts: I. The Case of Retraction of an Undercarriage about a Single Axis Available to Purchase

EXPERIENCE has shown that the common method of “laying out” geometrical problems on the drawing board leads to a large expenditure of man‐hours and, in general, a result of doubtful accuracy. This loss of accuracy is aggravated by scale, and results on large structures may be inaccurate by a prohibitive amount. Use of analytical geometry may be said to have two major advantages, therefore, (a) Less man‐hours required for the job, (b) Any desired standard of accuracy may be obtained.
