| TYPICAL RECORDS. Fig. 9. Reproduction (actual size) of a record obtained on the ram of a shaping machine with quick return motion. The "ripples" are due to imperfectly formed teeth in the driving gears. Fig. 10. The portion A—A of Fig. 9, as viewed through the microscope (Fig. 8). Fig. 11. The portion B—B of Fig. 9, photographically enlarged. 6 TYPICAL RECORDS. Photographically Enlarged. Fig. 12. Fig. 13. Records showing the vertical (Fig. 12) and horizontal (Fig. 13) accelerations of a normal pedestrian. (Magnification 12 linear). Fig. 14. Fig. 15. Records showing the vertical (Fig. 14) and horizontal (Fig. 15) accelerations of a pedestrian with an artificial leg. (Magnification 12 linear). Fig. 16. Record showing the vertical accelerations measured on an Armstrong-Siddeley motor car (18 h.p. mark I) travelling at 15 m.p.h. The tyres of the car were purposely blown up too hard in order to give a severe test to the springing on a particularly bad piece of road. (Magnification 10 linear). Fig. 17. Record taken on the same car, and under the same conditions as Fig. 16, but with the car travelling at 25 miles per hour. (Magnification 10 linear). 7 | ||
