Kammer, Savibull Foreword - The ninth Symposium attempted to review and appraise certain instruments which are employed in the study of shock and vibration. So far, no single instruments have been devised which is a universal shock indicator or which can serve as an all-purpose vibration meter. Just as the ship, the plane, and the tank differ in many of their functional characteristics, so do also some of the instruments which are used to investigate specific shock and vibration problems in those vehicles. Only through the proper use of suitable instruments are we able to provide quantitative information so urgently needed by the engineer, the designer, and the constructor. Therefore, in choosing a measuring device for a particular job, it might be well to ask the following questions: What information is needed from this study? What quantities must be measured to satisfy the need? What is the simplest and most practical method of obtaining the required measurements? Will this or that instrument best serve the purpose and provide the accuracy expected? It is hoped that some of the questions will be answered by critically examining and objectively discussing the various instruments which are described in these pages.
