Synopsis

This book presents a practical guide to the principles of designing diagrams, known as nomograms, for solving engineering and other formulas. The author emphasizes the growing importance of this method, especially for formulas that are complex to calculate and frequently used. The text goes beyond basic diagram-drawing methods, delving into the analysis of more complex engineering formulas, and utilizes the notation of third-order determinants for a more thorough understanding. While the author acknowledges the potential use of projective transformation, the book focuses on a more accessible approach and includes a dedicated appendix explaining determinants for those unfamiliar with this aspect of college algebra. The book introduces a new class of diagrams called "Diagrams of Adjustment," which are more general than traditional alignment diagrams and can be used for a wider range of formulas. The text explores the theoretical framework for incorporating scale factors and units of length into diagrams, ensuring practicality and enabling readers to create useful designs. The author includes numerous illustrative examples, avoiding trivial instances and providing detailed explanations for more complex cases. The book explores the advantages of representing formulas diagrammatically, including the immediate determination of any variable's value and the ability to analyze the rate of variation between variables. The author's extensive experience teaching this subject highlights its value as a supplementary course in applied mathematics and drafting. Overall, this book serves as a comprehensive guide to the field of nomography, offering readers the tools and knowledge necessary to effectively utilize this powerful method for solving engineering formulas.
