Book Description: 

This revised edition of an obvious Navy training manual leaves nothing to be desired in its presentation. Thorough in its coverage of basic theory, from the lever and inclined plane to internal combustion engines and power trains, it requires nothing more than an understanding of the most elementary mathematics.

Beginning with the simplest of machines — the lever — the text proceeds to discussions of the block and tackle (pulleys and hoists), wheel and axle, the inclined plane and the wedge, the screw, and different types of gears (simple, spur, bevel, herringbone, spiral, worm, etc.). A chapter on the concept of work discusses the measurement of work, friction, and efficiency; this is followed by investigations of power, force, and pressure, with explanations of the uses of scales, balances, gauges, and barometers. The fundamentals of hydrostatic and hydraulic machines (such as the hydraulic braking system and the hydraulic press) are discussed in detail.

The remaining chapters cover machine elements (bearings and springs), basic mechanisms (gear differential, couplings, cams, clutches), the internal combustion engine, and power trains (including explanations of various transmission systems — synchromesh, auxiliary, etc.).

Every concept is clearly defined, and discussions always build quickly from elementary theory to specific applications familiar to anyone interested in mechanics. Essential concepts, machine components, and techniques are clearly illustrated in more than 200 diagrams, drawings, and cross-sections that reveal inner workings — all help clarify an already clear and well-organized presentation even further.

Although initially designed for U.S. Naval Training Schools, this book can be used as an introductory text in mechanical engineering in standard technical schools. It will be precious even to lay readers who desire a basic knowledge of mechanics.

Handbook of Sensors and Actuators 

Book Description:

This authoritative new book focuses on recent developments in the instrumentation for sending voltages and currents. It covers new trends and challenges in the field, such as measurements of biocurrents, the increased speed of the components for data taking, and testing of computers, and integrated circuits where the measurement of rapid voltage and current variations on a microscopic geometrical scale is necessary. The first chapter concentrates on recent methods to sense voltages and currents, while the rest of the book investigates the applied side, covering, for instance, electrical power and energy measurements. The main purpose of this volume is to illustrate commonly employed techniques rather than track the scientific evolution and merits and, therefore, mainly covers patent literature aimed at industrial applications. It is an exciting addition, justifying the series’ claim to cover state-of-the-art developments in both the applied and theoretical fields of sensors and actuators.

The measurement of voltages and currents is a common task in the field of electricity and electronics. From a technical point of view, it is useful to identify schematically different steps of such a measurement. In the first step a voltage or a current is sensed, and intermediate steps such as amplification, transmission, and further treatment may follow to yield the result in the final step. Today in most cases, microprocessors perform the final steps of such measurements. Analog-to-digital converters digitize a voltage that is proportional to the value to be measured and a processor performs further computations and handles the storage and the display of the results. The prerequisite for such measurements is sensors or transducers that respond in a known way to the voltage or current to be measured. The emphasis of this book is put on recent developments in instrumentation for sensing voltages and currents.

Aside from the general trend towards smaller, cheaper, and more reliable instrumentation, new demands have arisen. New applications, like measurements of biocurrents, ask for higher sensitivities. Computers and integrated circuits pose new challenges. To exploit the increased speed of the components for data taking, suitable sensors are required. The accuracy that can be achieved depends more than ever on the first step, the acquisition of the raw data. The influence of the measurement process on the results becomes more crucial. Testing integrated circuits themselves is a completely new application. For such tests, one has to measure rapid voltage and current variations on very small geometrical scales. Here, as well as in traditional high-voltage applications, contactless measurements play an important role.

The organization of this book is as follows: In the first chapter different methods to sense voltages and currents are described. For the sake of completeness most commonly used methods are mentioned; we concentrate, however, on those developed recently. The chapters address the subject from the side of different applications in which voltages and currents are sensed.

Since the primary purpose of this publication is to illustrate commonly employed techniques rather than to track the scientific evolution and merits in particular fields, in general, those publications that illustrate a specific principle of measurement best have been cited. The citation of a particular reference does, therefore not imply that this is the first or most pertinent publication in the respective field.

Free PDF Download Dynamics of Mechanical Systems 

Book Description:

Mechanical systems are becoming increasingly sophisticated and require greater precision, improved reliability, and extended life. To meet the demand for advanced mechanisms and systems, present and future engineers must understand not only the fundamental mechanical components but also the principles of vibration, stability, and balance and the use of Newton’s laws, Lagrange’s equations, and Kane’s methods. The dynamics of mechanical systems provide a vehicle for mastering all of this. Focusing on the fundamental procedures behind dynamic analyses, the authors take a vector-oriented approach and lead readers methodically from simple concepts and systems through the analysis of complex robotic and biosystems. A careful presentation that balances theory, methods, and applications gives readers a working knowledge of configuration graphs, Euler parameters, partial and angular velocities, generalized speeds and forces, lower body arrays, and Kane’s equations. Evolving from more than three decades of teaching upper-level engineering courses, Dynamics of Mechanical Systems enables readers to obtain and refine skills ranging from performing insightful hand analyses to developing algorithms for numerical or computer studies. Ultimately, it prepares them to solve real-world problems and make future advances in mechanisms, manipulators, and robotics.

Book Description:

This volume is an information-packed reference for engineers on flow measuring techniques and instruments. Striking a balance between laboratory ideal and the realities of field experience, this handy tool provides a wealth of practical advice on the design, operation, and performance of a broad range of flowmeters. The book begins with a brief review of fluid mechanics principles, how to select a flowmeter, and a variety of calibration methods. Each of the following chapters is devoted to a class of flowmeters and includes detailed information on design, applications, installation, calibration, operation, and advantages and disadvantages. Among the flowmeters discussed are orifice plate meters, venturi meter and standard nozzles, critical flow venturi nozzles, positive displacement flowmeters, turbine and related flowmeters, vortex shedding and fluidic flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, and coriolis flowmeters. Also covered are mass flow measurements using multiple sensors, thermal flowmeters, angular momentum devices, probes, and modern control systems. Many chapters conclude with an appendix on the theory behind the techniques discussed. It will be a valuable reference for practicing engineers and will also interest researchers in mechanical, chemical and aerospace engineering.
