A handbook of physics measurements; Vol. II: Vibratory motion, sound, heat, electricity and magnetism

Vibratory Motion, Sound, Heat, Electricity and Magnetism – is the second volume of “A Handbook of Physics Measurements”, which was published in 1918 and written by Ervin S. Ferry. This volume contains those measurements of the magnitudes of vibrational motion, sound, heat, electricity and magnetism, which, as experience has shown, are most accessible to university and industrial laboratories. In selecting from a large number of tests tested in practical laboratory conditions, due consideration has been given to the specific definitions currently required by science and industry, the degree of accuracy easily achievable, and the time required to determine them, conduct the experiment and calculate the result. In addition to the standard experiments with heat, the mechanical engineer will be particularly interested in methods for determining the savings produced by steam pipe coatings, the calorific value of coal, and the calorific value of gas. All physical definitions of electricity and magnetism, which are usually made by students studying electrical engineering, are described in detail. In addition, a significant place is devoted to the analysis of damped oscillations and harmonic waves. This work is of great importance for students of alternating current phenomena. In many laboratories, little attention is paid to sound measurements. However, the recent war has so strongly emphasized the usefulness of such work that no apologies are made for including a number of experiments in this topic. As in the first volume of Fundamental Measurements, Properties of Matter and Optics, each chapter is divided into two parts. The first part includes definitions, a description of the apparatus, a general theory of methods, and the derivation of equations used in determining the quantities considered in the chapter. In the second part of the chapter, each definition is described in detail in relation to the theory and conduct of the experiment, as well as the calculation of the result. This book satisfies the industrial need for accurate temperature knowledge, especially where continuous automatic recording of the temperature state continues for a certain period of time.
