MR. McCAIN enumerates in the simplest possible form some outstanding features of the new automobile-dynamics, and gives practical commercial reasons for his conclusions.As referred to in the paper, streamlining is the reshaping of bodies to reduce air resistance at a commercial speed of about 45 m.p.h. An analysis of this subject is presented, and the effects of a redistribution of passengers and units are discussed. Riding-quality model-test results and weight distribution are commented upon. A bibliography of streamlining is included.The overdrive is considered by Mr. McCain as part of the airflow car, and the curves show that-with the overdrive-a greater car speed can be reached under favorable wind-conditions, exceeding the curve values, without an excessive engine-speed. Forces acting upon planetary overdrive gears are treated in the Appendix.Much remains to be done toward reduction of wind resistance, in Mr. McCain's opinion. He says that an ideally streamlined body would be too long to park and turn sharply in city traffic, and would involve an extra amount of weight that would constitute a drag against acceleration. Further, that a long tail involves more waste space per wheelbase, and, with the engine in front, does not adapt itself to readily usable baggage compartments.MR.
