Bøker av Erik Oberg

This volume contains a vintage guide to machine design and workshop practise, with this edition focusing on screw thread tools and gauges. A gauge or gage is a scientific or engineering device that is used to measure or to display certain dimensional information. A wide range of such tools exist which serve this function, ranging from simple pieces of material against which sizes can be measured to large and complex pieces of machinery. With helpful diagrams, useful measurement tables, and simple explanations, this volume would make for fantastic reference guide for engineers and handy addition to collections of allied literature. Contents include: "Screw Thread Systems, by Erik Oberg", "Making Thread Tools, by E. A. Johnson", "Tools for Accurate Thread Cutting, by Jos. M. Stabel", "Making Thread Gages, by. A. L. Monrad", "Measuring Screw Thread Diameters, by Walter Cantelo", etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.

"Solution of Triangles" is a concise treatise on the use of formulas and trigonometry within engineering. Originally designed for use in machine shops, tool rooms, and drafting rooms, it offers simple, practical information on the solution of triangles and related formulas for those engaged in machine work and allied fields. This vintage book will appeal to those with an interesting workshop practice, and it is not to be missed by collectors of related literature. Contents include: "The Use of Formulas", "Angles and Angular Measurements", "Positive and Negative Quantities", "Functions of Angeles", "Tables of Trigonometric Functions", "Practical Applications of Trigonometric Formulas", "Right-angled Triangles", "Solution of Oblique-angled Triangles", "Summary of Formulas for Solution of Triangles", etc. Many vintage books such as this are increasingly scarce and expensive.
