STREAMLINING
Discussing streamlining recently a prominent British engineer said that little had been done in connection with cars sold to the public, probably because there had been-more important improvements to be made than that of discovering the shape offering the least resistance to the air. The possibilities, however, were enormous. A normal type of closed car, running at 35 m.p.h., required 8 h.p. to overcome rolling resistance, and another 8 h.p. to overcome air resistance. At 70 m.p.htlie figures became 16 and 61, while at SO m.p.h. less than 19 h.p. was required for road resistance and 100 h.p. for air displacement. It is interesting to note that, at the moderate cruising speed of 35 m.p.h. half the power developed is being used to force a passage through the air. and at very frequent bursts of speed about two-thirds of the power is being wasted in overcoming air resistance.
