Detailed Mechanical Design:A Practical Guide James G. Skakoon
The idea of engineering has been present since prehistoric times when humans started shaping important creations like the lever, wheel and pulley. Every invention is described with the contemporary explanation of basic engineering principles of mechanics. The word engineering has been derived from the term engineer and dates back to around recently 1325 and the word engineer in those times meant or denoted to someone who was the constructor of engines. The term engine has actually become obsolete as it is now refers to a military machine or in a more detailed description it was a mechanical apparatus used in wars. The word engine comes from the Latin word ingenium which means intrinsic quality, particularly cerebral power, as in an ingenious creation. As time passed more structures like houses, buildings and bridges were invented, which required new engineering techniques. The term civil engineering was introduced to differentiate among those who were experts in building military machines and was called military engineering. The term engineering is extremely broad and comprises a variety of different types of engineering, each focusing on specific parts of technology, applied science and applications. 1.

Fatigue and wear are the most damaging phenomena affecting machines since they result in some 90% of breakdowns. This tutorial book systematically develops a unified overview, named tribo-fatigue, which aims to address the complex wear-fatigue damages. Tribo-fatigue synthesizes aspects of three disciplines: mechanical fatigue, tribology, and reliability of mechanical systems. Tribo-fatigue opens new perspectives for increasing the durability of machines according to the most important criteria of their serviceability. Detailed damage measurement and wear-fatigue tests that enable engineers to design more durable and reliable systems are developed. The book is intended for advanced students, researchers and engineers.
The science and technology related to semiconductors have received significant attention for applications in various fields including microelectronics, nanophotonics, and biotechnologies. Understanding of semiconductors has advanced to such a level that we are now able to design novel system complexes before we go for the proof-of-principle experimental demonstration. This book explains the experimental setups for optical spectral analysis of semiconductors and describes the experimental methods and the basic quantum mechanical principles underlying the fast-developing nanotechnology for semiconductors. Further, it uses numerous case studies with detailed theoretical discussions and calculations to demonstrate the data analysis. Covering structures ranging from bulk to the nanoscale, it examines applications in the semiconductor industry and biomedicine. Starting from the most basic physics of geometric optics, wave optics, quantum mechanics, solid-state physics, it provides a self-contained resource on the subject for university undergraduates. The book can be further used as a toolbox for researching and developing semiconductor nanotechnology based on spectroscopy.
Unrivalled in its coverage and unique in its hands-on approach, this guide to the design and construction of scientific apparatus is essential reading for every scientist and student of engineering, and physical, chemical, and biological sciences. Covering the physical principles governing the operation of the mechanical, optical and electronic parts of an instrument, new sections on detectors, low-temperature measurements, high-pressure apparatus, and updated engineering specifications, as well as 400 figures and tables, have been added to this edition. Data on the properties of materials and components used by manufacturers are included. Mechanical, optical, and electronic construction techniques carried out in the lab, as well as those let out to specialized shops, are also described. Step-by-step instruction supported by many detailed figures, is given for laboratory skills such as soldering electrical components, glassblowing, brazing, and polishing.
An up-to-date, self-contained introduction to the theory and applications of the finite element method This thoroughly revised classic engineering textbook offers a broad-based overview of the finite element method. Written by a world-renowned mechanical engineering researcher and author, the book shows, step-by-step, how to calculate numerical solutions to steady-state as well as time-dependent problems. You also get detailed problems with worked-out solutions and downloadable programs that can be used and modified for real-world situations. Special attention is paid to applications that are important in bioengineering, fluid and thermal sciences, structural mechanics, and a host of applied sciences. Introduction to the Finite Element Method, Fourth Edition, covers: .Mathematical preliminaries and classical variational methods .1-D finite element models of second-order differential equations .Applications to 1-D heat transfer and fluid and solid mechanics problems .Finite element analysis of beams and circular plates .Plane trusses and frames .Eigenvalue and time-dependent problems in 1-D .Numerical integration and computer implementation in 1-D .Single-variable problems in two dimensions .2-D interpolation functions, numerical integration, and computer implementation in 2-D .Flows of viscous incompressible fluids .Plane elasticity .3-D finite element analysis
This augmented and updated fourth edition introduces a new complement of computational tools and examples for each chapter and continues to provide a grounding in the tensor-based theory of elasticity for students in mechanical, civil, aeronautical and biomedical engineering and materials and earth science. Professor Gould´s proven approach allows faculty to introduce this subject early on in an educational program, where students are able to understand and apply the basic notions of mechanics to stress analysis and move on to advanced work in continuum mechanics, plasticity, plate and shell theory, composite materials and finite element mechanics. With the introductory material on the use of MATLAB, students can apply this modern computational tool to solve classic elasticity problems. The detailed solutions of example problems using both analytical derivations and computational tools helps student to grasp the essence of elasticity and practical skills of applying the basic mechanics theorem.
Introducing Human Design, the revolutionary system that reveals the personality ´blueprint´ of who you were born to be. Using the precise details of your birth, it´s more accurate than astrology. And with a free CD you can map your own life chart, and those of your friends and family. You´ll never read your horoscope again. Forget your sign, what´s your design? Would you like to know how to make the best decisions and follow your correct path in life? Would you like to know how you best interact with people, both professionally and personally? Would you like to know who you really are? Human Design is an exciting new profiling system that answers all these questions by pinpointing your personality ´blueprint´. According to Human Design, we are each born with an inbuilt individuality as unique as our fingerprint - accessed simply from the date, time and location of our birth. Using this information, Human Design produces a ´life chart´, revealing a remarkably detailed and accurate picture of your personality blueprint, including your strengths and limitations, people you work best with, how you communicate - in short who you were designed to be from birth. Chetan Parkyn, an ex-mechanical engineer, is the most successful practitioner of Human Design in the world. Here he launches his first book and CD as an introductory guide to interpreting your Human Design chart and how to apply it to your life to release your true potential. Once you know which of the 5 personality types you are, from there you can discover your detailed personality blueprint including: - whether you are designed with creative or organisational energy - your style of decision-making and how it can maximise your opportunities -how you interact with people socially or fit into a team at work - are you designed to be a guider or a follower - how you emotionally and mentally respond to challenges and problem-solving The power of the Human Design system is surprising thousands of people around the world with its staggering accuracy and relevance, and asks the question: Are you living your Human Design?
In this book work is to carried out on mechanical design and analysis of the hub for a 1kW Small Wind Turbine System. The rotating blades extract the kinetic energy available in the free air stream, convert it into useful shaft power and transfer it to the generator. In the present Small Wind Turbine system, the blades are directly coupled to the generator casing. The hub acts as the interface between the rotor blades of a wind turbine system (WTS) and the rotating outer casing of the generator. It is therefore a very critical component of the WTS as it transfers the severe aerodynamic, gravitational and inertial loads acting on the rotor system. A detailed design of the hub has been carried out. The design loads have been quantified based on guidelines of IEC 61400-2. Conceptual design has been carried out and a casting model using AUTOCAD INVENTOR modelling software. Detailed designs for the respective hubs have been carried out. FEM analysis of both the proposed hub models have been done using Finite Element modelling tool HYPERMESH and NASTRAN solver.
This book details the basic concepts and the design rules included in Eurocode 3 ?Design of steel structures? Part 1-8 ?Design of joints?. Joints in composite construction are also addressed through references to Eurocode 4 ?Design of composite steel and concrete structures? Part 1-1 ?General rules and rules for buildings?. Attention has to be duly paid to the joints when designing a steel or composite structure, in terms of the global safety of the construction, and also in terms of the overall cost, including fabrication, transportation and erection. Therefore, in this book, the design of the joints themselves is widely detailed, and aspects of selection of joint configuration and integration of the joints into the analysis and the design process of the whole construction are also fully covered. Connections using mechanical fasteners, welded connections, simple joints, moment-resisting joints and lattice girder joints are considered. Various joint configurations are treated, including beam-to-column, beam-to-beam, column bases, and beam and column splice configurations, under different loading situations (axial forces, shear forces, bending moments and their combinations). The book also briefly summarises the available knowledge relating to the application of the Eurocode rules to joints under fire, fatigue, earthquake, etc., and also to joints in a structure subjected to exceptional loadings, where the risk of progressive collapse has to be mitigated. Finally, there are some worked examples, plus references to already published examples and to design tools, which will provide practical help to practitioners.
