Strength of Materials

2008-11-15T23:49:00.000-08:00

Title : Strength of Materials
Year : 2004
Writer : Surya N. Patnaik & Dale A. Hopkins
Published by ELSEVIER

Strength of materials is a common core course requirement in U.S. universities (and those elsewhere) for students majoring in civil, mechanical, aeronautical, naval, architectural, and other engineering disciplines. The subject trains a student to calculate the response of simple structures. This elementary course exposes the student to the fundamental concepts of solid mechanics in a simplified form. Comprehension of the principles becomes essential because this course lays the foundation for other advanced solid mechanics analyses. The usefulness of this subject cannot be overemphasized because strength of materials principles are routinely used in various engineering applications. We can even speculate that some of the concepts have been used for millennia by master builders such as the Romans, Chinese, South Asian, and many others who built cathedrals, bridges, ships, and other structural forms. A good engineer will benefit from a clear comprehension of the fundamental principles of strength of materials. Teaching this subject should not to be diluted even though computer codes are now available to solve problems.
The theory of solid mechanics is formulated through a set of formidable mathematical equations. An engineer may select an appropriate subset to solve a particular problem. Normally, an error in the solution, if any, is attributed either to equation complexity or to a deficiency of the analytical model. Rarely is the completeness of the basic theory questioned because it was presumed complete, circa 1860, when Saint-Venant provided the strain formulation, also known as the compatibility condition. This conclusion may not be totally justified since incompleteness has been detected in the strain formulation. Research is in progress to alleviate the deficiency. Benefits from using the new compatibility condition have been discussed in elasticity, finite element analysis, and design optimization. In this textbook the compatibility condition has been simplified and applied to solve strength of materials problems.

Published by McGRAW-HILL

The sixth edition of the Building Design and Construction Handbook maintains the original objectives of previous editions which gained widespread acceptance amongusers. These objectives are to provide in a single volume a compendium of the bestof the current knowledge and practices in building design and construction.This information would be of greatest use to those who have to make decisionsaffecting the selection of engineering materials and construction methods.

Emphasisis placed on fundamental principles and practical applications, with special attentionto simplified procedures. Frequent reference is made to other sources where additional authoritative information may be obtained, such as architectural and engineeringsocieties, manufacturers associations, and the Internet. An extensive indexis provided to assist the reader in locating topics within the book.Many new contributors and sections have been added in this edition to providethe reader with the latest developments and knowledge in the building industry.These developments include the expansion of data technology and communication systems within the building system, revisions to wind and seismic loadings, and anexpansion of the information on fire sprinkler systems.

To present the necessary information in a single volume, obsolete and less-important information in the earliereditions has been deleted.The editor is very grateful to the contributors, not only for their care, skill, andknowledge used in preparing the sections, but also for their considerable sacrificesof personal time to prepare the sections.

CentrifugaI Pumps

2008-11-15T23:03:00.000-08:00

Title : Know and Understand Centrifugal Pumps
Year : 2003
Writter: Larry Bachus and Angel Custodio
Published by Elsevier Ltd

Very few industrial pumps come out of service and go into the maintenance shop because the volute casing or impeller split down the middle, or because the shaft fractured into four pieces. The majority of pumps go into the shop because the bearings or the mechanical seal failed. Most mechanics spend their time at work time greasing and changing bearings, changing pump packing, and mechanical seals. The mechanical engineers spend their time comparing the various claims of the pump manufacturers, trying desperately to relate the theory learned at the University with the reality of the industrial plant. Purchasing agents have to make costly decisions with inadequate information at their disposal. Process engineers and operators are charged with maintaining and increasing production.
The focus of industrial plant maintenance has always been that the design is correct, and that the operation of the pumps in the system is as it should be. In this book, you will see that in the majority of occasions, this is not true. Most of us in maintenance spend our valuable time, just changing parts, and in the best of cases, performing preventive maintenance, trying to diminish the time required to change those parts.
We almost never stop to consider what is causing the continual failure of this equipment. This book will help you to step away from the fireman approach, of putting out fires and chasing emergencies.
This book is directed toward the understanding of industrial pumps and their systems. It won’t be a guide on how to correctly design pumps, nor how to rebuild and repair pumps. There are existing books and courses directed toward those themes. By understanding the real reasons for pump failure, analyzing those failures, and diagnosing pump behavior through interpretation of pressure gauges, you can achieve productive pump operation and contain maintenance costs. This book will serve as a guide to STOP repairing industrial pumps.
