Sinopsis

Flows are beautiful and complex. A swollen creek tumbles over rocks and through crevasses, swirling and foaming. A child plays with sticky taffy, stretching and reshaping the candy as she pulls and twists it in various ways. Both the water and the taffy are fluids, and their motions are governed by the laws of nature. Our goal is to introduce readers to the analysis of flows using the laws of physics and the language of mathematics. On mastering this material, readers can harness flow to practical ends or create beauty through fluid design.

In this text we delve into the mathematical analysis of flows; however, before beginning, it is reasonable to ask if it is necessary to make this significant mathematical effort. After all, we can appreciate a flowing stream without understanding why it behaves as it does. We also can operate machines that rely on fluid behavior drive a car, for example without understanding the fluid dynamics of the engine. We can even repair and maintain engines, piping networks, and other complex systems without having studied the mathematics of flow. What is the purpose, then, of learning to mathematically describe fluid behavior?

The answer is quite practical: Knowing the patterns that fluids form and why they are formed, and knowing the stresses that fluids generate and why they are generated, is essential to designing and optimizing modern systems and devices. The ancients designed wells and irrigation systems without calculations, but we can avoid the waste and tedium of the trial-and-error process by using mathematical models. Some inventions, such as helicopters and lab-on-a-chip reactors, are sufficiently complex that they never would have been designed without mathematical models. Once a system is modeled accurately, it is then straightforward to calculate operating variables such as flow rates and pressures or to evaluate proposed design or operating changes. A mathematical understanding of fluids is important in fields such as airplane and space flight, biomedicine, plastics processing, volcanology, enhanced oil recovery, pharmaceuticals, environmental remediation, green energy, and astrophysics. Although a trial-and-error approach can get us started in fluids-related problems, significant progress requires formal mathematical analysis.

Download PDF Automobile Mechanical and Electrical Systems Automotive Technology: Vehicle Maintenance and Repair by Tom Denton

Sinopsis

The rear engine design has not been very popular but it was used for the best selling car of all time: the VW Beetle. The advantages are that weight is placed on the rear wheels, giving good grip, and the power unit and drive can be all one assembly. One downside is that less room is available for luggage in the front. The biggest problem is that handling is affected because of less weight on the steered wheels. Flat-type engines are the most common choice for this type of vehicle.

Fitting the engine in the mid-position of a car has one major disadvantage: it takes up space inside the vehicle. This makes it impractical for most ‘normal’ vehicles. However, the distribution of weight is very good, which makes it the choice of high-performance vehicle designers. A good example is the Ferrari Testarossa. Mid-engine is the term used to describe any vehicle where the engine is between the axles, even if it is not in the middle.

Download PDF Advanced Mathematics and Mechanics Applications Using Matlab Third Edition by Howard B. Wilson

Sinopsis

This book presents variousMATLAB applications in mechanics and applied mathematics. Our objective is to employ numerical methods in examples emphasizing the appeal of MATLAB as a programming tool. The programs are intended for study as a primary component of the text. The numerical methods used include interpolation, numerical integration, Þnite differences, linear algebra, Fourier analysis, roots of nonlinear equations, linear differential equations, nonlinear differential equations, linear partial differential equations, analytic functions, and optimization methods. Many intrinsic MATLAB functions are used along with some utility functions developed by the authors. The physical applications vary widely from solution of linear and nonlinear differential equations in mechanical system dynamics to geometrical property calculations for areas and volumes.
 

For many years FORTRAN has been the favorite programming language for solving mathematical and engineering problems on digital computers. An attractive alternative is MATLAB which facilitates program development with excellent error diagnostics and code tracing capabilities. Matrices are handled efÞciently with many intrinsic functions performing familiar linear algebra tasks. Advanced software features such as dynamic memory allocation and interactive error tracing reduce the time to get solutions. The versatile but simple graphics commands in MATLAB also allow easy preparation of publication quality graphs and surface plots for technical papers and books. The authors have found that MATLAB programs are often signifantly shorter than corresponding FORTRAN versions. Consequently, more time is available for the primary purpose of computing, namely, to better understand physical system behavior.
 

The mathematical foundation needed to grasp most topics presented here is covered in an undergraduate engineering curriculum. This should include a grounding in calculus, differential equations, and knowledge of a procedure oriented programming language like FORTRAN. An additional course on advanced engineering mathematics covering linear algebra, matrix differential equations, and eigenfunction solutions of partial differential equations will also be valuable. The MATLAB programs were written primarily to serve as instructional examples in classes traditionally referred to as advanced engineering mathematics and applied numerical methods. The greatest beneÞt to the reader will probably be derived through study of the programs relating mainly to physics and engineering applications. Furthermore, we believe that several of the MATLAB functions are useful as general utilities. Typical examples include routines for spline interpolation, differentiation, and integration; area and inertial moments for general plane shapes; and volume and inertial properties of arbitrary polyhedra. We have also included examples demonstrating natural frequency analysis and wave propagation in strings and membranes.
 

MATLAB is now employed in more than two thousand universities and the user community throughout the world numbers in the thousands. Continued growth will be fueled by decreasing hardware costs and more people familiar with advanced analytical methods. The authors hope that our problem solutions will motivate analysts already comfortable with languages like FORTRAN to learnMATLAB. The rewards of such efforts can be considerable.

Download PDF Mechanics of Composite Materials with MATLAB by George Z. Voyiadjis

Sinopsis

There are many excellent textbooks available on mechanics of fiber-reinforced composite materials like those in [1–12]. Therefore this book will not present any theoretical formulations or derivations of mechanics of composite materials. Only the main equations are summarized for each chapter followed by examples. In addition only problems from linear elastic structural mechanics are used throughout the book.
 

The main subject of this book is the mechanics of fiber-reinforced composite materials. These materials are usually composed of brittle fibers and a ductile matrix. The geometry is in the form of a laminate which consists of several parallel layers where each layer is called a lamina. The advantage of this construction is that it gives the material more strength and less weight. The mechanics of composite materials deals mainly with the analysis of stresses and strains in the laminate. This is usually performed by analyzing the stresses and strains in each lamina first. The results for all the laminas are then integrated over the length of the laminate to obtain the overall quantities. In this book, Chaps. 2–6 deal mainly with the analysis of stress and strain in one single lamina. This is performed in the local lamina coordinate system and also in the global laminate coordinate system. Laminate analysis is then discussed in Chaps. 7–9. The analysis of a lamina and a laminate in these first nine chapters are supplemented by numerous MATLAB examples demonstrating the theory in great detail. Each MATLAB example is conducted in the form of an interactive MATLAB session using the supplied MATLAB functions. Each chapter of the first nine chapters has a set of special MATLAB functions written specifically for each chapter. There are MATLAB functions for lamina analysis and for laminate analysis.
 

In Chap. 10, we illustrate the basic concepts of the major four failure theories of a single lamina. We do not illustrate the failure of a complete laminate because this mainly depends on which lamina fails first and so on. Finally, Chaps. 11 and 12 provide an introduction to the advanced topics of homogenization and damage mechanics in composite materials, respectively. These two topics are very important and are currently under extensive research efforts worldwide.
 

The analyses discussed in this book are limited to linear elastic composite materials. The reader who is interested in advanced topics like elasto-plastic composites, temperature effects, creep effects, viscoplasticity, composite plates and shells, dynamics and vibration of composites, etc. may refer to the widely available literature on these topics.

Download PDF TRIBOLOGY OF ABRASIVE MACHINING PROCESSES by Ioan D. Marinescu

Sinopsis

Abrasive machining processes are manufacturing techniques which employ very hard granular particles in machining, abrading, or polishing to modify the shape and surface texture of manufactured parts. A wide range of such processes is mostly used to produce high quality parts to high accuracy and to close tolerances. Examples range from very large parts such as machine slideways to small parts such as contact lenses, needles, electronic components, silicon wafers, and ball bearings. While accuracy and surface texture requirements are common reasons for selecting abrasive processes, there is another common reason. Abrasive processes are the natural choice for machining and finishing hard materials and hardened surfaces.

Most abrasive processes may be categorized into one of four groups: (i) grinding, (ii) honing, (iii) lapping, (iv) polishing. This is not a completely inclusive list, but the four groups cover a wide range of processes and are a sufficient representation for a study of fundamental characteristics of such processes. These four groups are illustrated in Fig. 1.1. Grinding and honing are processes which employ bonded or fixed abrasives within the abrasive tool, whereas lapping and polishing employ free abrasive particles, often suspended in a liquid or wax medium.

The subject Machine Design is the creation of new and better machines and improving the existing ones. A new or better machine is one which is more economical in the overall cost of production and operation. The process of design is a long and time consuming one. From the study of existing ideas, a new idea has to be conceived. The idea is then studied keeping in mind its commercial success and given shape and form in the form of drawings. In the preparation of these drawings, care must be taken of the availability of resources in money, in men and in materials required for the successful completion of the new idea into an actual reality. In designing a machine component, it is necessary to have a good knowledge of many subjects such as Mathematics, Engineering Mechanics, Strength of Materials, Theory of Machines, Workshop Processes and Engineering Drawing

Fluid mechanics is concerned with the behaviour ofliquids and gases at rest and in motion. The proper understanding of mechanics of fluids is important in many branches of engineering: in biomechanics the flow of blood is of interest; ocean currents require a knowledge offluid mechanics; chemical processing of plants require a thorough knowledge offluid mechanics; aeronautical engineers require knowledge offlow of air over the aircraft to reduce drag and increase lift; mechanical engineers require knowledge of fluid propel1ies to design pumps, water turbines, gas turbines and rockets; civil engineers require fluid mechanics to study river currents and erosion; and environmentalists require knowledge offluid properties for solving pollution problems of air and water to control flood, irrigation channels, etc. There are special ised books on fluid mechanics for each of these areas and therefore this book will present only general properties of fluid flow.

Sinopsis

In this introductory chapter, we present the basic concepts commonly used in the analysis of fluid flow. We start this chapter with a discussion of the phases of matter and the numerous ways of classification of fluid flow, such as viscous versus inviscid regions of flow, internal versus external flow, compressible versus incompressible flow, laminar versus turbulent flow, natural versus forced flow, and steady versus unsteady flow. We also discuss the no-slip condition at solid–fluid interfaces and present a brief history of the development of fluid mechanics.

After presenting the concepts of system and control volume, we review the unit systems that will be used. We then discuss how mathematical models for engineering problems are prepared and how to interpret the results obtained from the analysis of such models. This is followed by a presentation of an intuitive systematic problem-solving technique that can be used as a model in solving engineering problems. Finally, we discuss accuracy, precision, and significant digits in engineering measurements and calculations.
