This book is a comprehensive manual on the principles of mechanics and geometry as they apply to construction trades. With detailed explanations and illustrations, the author explains how to apply these principles to different types of construction projects. Whether you're a practicing tradesman or a student studying the trades, this book is indispensable.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.This work is in the "public domain in the United States of America, and possibly other nations.

Around 1970 the planet and our occupation of it was pretty much a situation of balance; the biospheric absorptive and recycling capacity coping with resource uptake and waste discard. Since then a doubled human mass and carbon gas overload has spawned the greenhouse effect that has activated ice field melt, savannah extension, rainforest depletion, waste accumulation and species extinction. Resilience is a prevent-and-adapt advisory. It evokes limits for the growth-on-growth ideology and print money process. It provokes a births-deaths equilibrium, reduced fossil carbon consumption, rainforest restoration and waste recycling. It is about future-proofing the next generation.

Once more, Astragal Press has rescued an old and rare book from obscurity, allowing for the broad circulation of information previously limited to the select few who could afford access. This book, first published in 1881, was written about the use of the first standard slide rule made in the United States: a Mannheim-type slide rule made by Stephens Co., a mjor rule manufacturer. Included in Riddell’s book, aimed primarily at carpenters and joiners, is a wealth of fascinating instruction on the use of the slide rule in everything from making the calculations necessary for constructing circular porches and spiral stairways, to calculating wages owed or the cost of hauling lumber. Included, as well, are lovely plates illustrating various geometric and trigonometric calculations used in construction. As a source book, it should be of great interest and value to tool collectors, slide rule enthusiasts, and woodworkers.
