An Engineering Companion to Mechanics of Materials is the first volume in the Momentum Press collection The Modern Engineering Companions: A Systems Approach to the Study of Engineering. In Mechanics of Materials, we apply the intuitive "systems approach" to learning, the advantages of which are several. The student first gets a broad overview of the entire subject rather than the narrow piecemeal vision afforded by the traditional "component approach" common to most engineering texts. Mechanics of Materials comes with additional features to improve student learning, including Common Confusing Concepts (C3) noted and clarii ed, indication of key concepts, side bar discussions, worked examples, and exercises for developing engineering intuition. The Companions are intended as a supplementary resource to help both undergraduate, graduate, and post-graduate students better learn and understand engineering concepts.

This two-volume book comprises a comprehensive up-to-date body of knowledge that provides a total in-depth insight into valve and actuator technology - looking not just at control valves, but a whole host of other types including: check valves, shut-off valves, solenoid valves, and pressure relief valves. Research studies within the process industry routinely indicate that the fluid control valve is responsible for 60 to 70% of poor-functioning control systems. Furthermore, valves in general are consistently wrongly selected, regularly misapplied, and often incorrectly installed. A methodology is presented to ensure the optimum selection of size, choice of body and trim materials, components, and ancillaries. Whilst studying the correct procedures for sizing, readers will also learn the correct procedures for calculating the spring 'wind-up' or 'bench set'. Maintenance issues also include: testing for deadband/hysteresis, stick-slip and non-linearity; on-line diagnostics; and signature analysis. Written in a detailed but understandable language, the two volumes are presented in a form suitable for both the beginner, with no prior knowledge of the subject, and the more advanced specialist.

This straightforward guide to compressors seeks to unveil a lot of myths surrounding compressors. In this book, we will be looking at most types of compressors, including the centrifugal compressors, the air compressors, and of course the most troublesome of all compressors, the reciprocating compressors.Having a compressor with minimal operating problems does not only depend on the selection of the right type and size for your job. Detailed specifications of all auxiliary equipment and operating conditions, as well as keeping constant vigilance over the engineering and installation is imperative. The Simple Guide will explain in a simple yet definitive manner which compressor type is best used for which job and what it can produce.
