1949 MEASURING SHOCK 585 not too long so that this frame-interval determination does not have to be repeated. The frames are also numbered from a chosen starting point, marking every tenth frame. Next the tape is measured to establish the dimensional scale factor which will enable us to find the actual displacement in inches. Then a tabulation is made, measuring the displacement of one or more parts, which is a somewhat tiresome 0.9 P OB 0 •_ -20 4567 TIME IN MILLISECONDS Fig. 8 — Typical data obtained from film. and monotonous job. The tabulated data are then plotted and the final results are time-displacement curves, which are then processed further to obtain supplementary information (Fig. 8) . Some of the advantages of this method of recording are: 1. The high-speed motion picture provides a complete over-all view of a group of complex motions occurring at very small time intervals.
