Solutions to Irodov’s Problems in General Physics, Vol II

Solutions to Irodov’s Problems in General Physics, Vol II

Abhay Kumar Singh

ISBN: 13: 978-81-265-2077-0

Price: 299/Pages: 440

About the book

Irodov problems are considered the trickiest and the most comprehensive set of problems in physics the world over. In fact, some problems combine multiple concepts of physics, which makes these problems unique.

Solutions to I.E. IRODOV’S problems in General Physics, available in two volumes, are meant for those dedicated physics students who face the challenge of solving numerical problems, particularly IIT-JEE aspirants. The two volumes provide the complete solutions for each of the 1878 problems in I.E. IRODOV’s original question book, along with final answers.

The solutions presented in this book are crisp, and guaranteed to make you think beyond the box. This book is exactly what you need to establish a strong foundation for discovering the beauty of physics and cracking any entrance exam in India.

 

The second volume contains solutions related to the following topics:

  • Oscillations and Waves
  • Optics and Atomic
  • Nuclear Physics

Salient Features

  • Comprehensive solutions for each and every Irodov problem
  • Explanatory diagrams for 70% problems
  • Answers are in SI units in accordance with the rules of approximation and accuracy.

 Some advantages that the book will have in the market:

1. It is the only one of its kind, because no other book offers solutions to all of Irodov’s problems (826)

2. Experts find that solutions given byAbhay Kumar Singh are crisper.

3. The third edition builds on the success of earlier editions in terms of  the accuracy of solutions.

4. The author is respected and experienced. His name is synonymous with Irodov solutions among IIT-JEE aspirants.

5. The figures are better in quality because they are digitally-printed. The earlier editions had hand-drawn figures.

6. Irodov’s problems are the most exhaustive test of a student’s  understanding of concepts, because they sometimes use more than 1 or 2 concepts in the same problem, which is not the case with ordinary numerical problems.

About the author

About the Technology

If we trace the history of electronic technology over the last six decades, we see that the discovery of the transistor and the development of the integrated circuit (IC) are the key milestones. However, it is the miniaturization and the ensuing VLSI technology that really created the electronic, the computer and communications revolution. It is only more recently, i.e., in the last couple of decades, that the technology of miniaturization has been extended to mechanical systems; and now, we have microsystem revolution. This is also complemented by the advances in smart materials and systems.

A microsystem is a system that integrates, on a chip or in a package, one or more of many microdevices: sensors, actuators, electronics, computation, communication, control, power generation, chemical processing, biological reactions, and many more which constitute microsystems. It is now clear that the functionality of such an integrated system will be not only far superior to any other engineered system that we know at the macro scale but achieve things beyond those achievable by macro-scale integrated systems. Smart micro electromechanical systems (MEMS) refer to a collection of micro sensors and actuators that can sense their environment and have the ability to react to changes in that environment with the use of a microcircuit control. Such microsystems include, in addition to the conventional microelectronics, packaging, integrated antenna structures for command signals, microelectromechanical structures for desired sensing and actuating functions. In order to act upon the environment, the magnitude of the micromachined actuators is not large enough. Using macro-scale actuators is not appropriate because they defeat the purpose of miniaturization, cost-effective batch-processing, etc. Hence, there is a need to integrate smart material based actuators with microsystems. This trend is currently witnessed in this field as it moves beyond microsensors, which has been the main emphasis in microsystems so far.

Micro and smart system technologies have immense application potential in many fields. In the coming decades, scientists and engineers would be required to design and develop such systems for varied applications. It is essential then that graduating engineers must be exposed to the underlying science and technology.

Key Features

  • This book emphasizes analytical and computational modeling.
  • It includes in-depth discussion of mechanics, coupled multi-physics, electronics, control, and scaling effects as well as finite element analysis.
  • Relating all of the above to particular examples of microelectromechanical systems (MEMS) and smart devices is a highlight of this book.
  • Complementing the modeling aspects, the book includes organized summaries of a variety of devices and systems, details of packaging and integration, and case-studies of representative devices.
  • Prior disciplinary background is not assumed in presenting the material.
  • Many worked-out examples, context-relevant problems within the chapters, and practice exercises are included in all chapters. It is thus suitable for self-study by practicing engineers and researchers in many disciplines.
  • Unavailability of a book that covers both micro and smart systems at the fundamental level.
  • Excellent pedagogy with:
  • 230+ Illustrations
  • 25 Tables
  • 100+ Exercise Questions
  • 45 “Your Turn” questions for students wanting to invest time in researching.
  • About 50 Problems and Examples within chapters 

About the Book

This book essentially deals with the basics of microsystem technology and is intended principally as a textbook at the undergraduate level; however, it can also be used as background book at the postgraduate level. The book makes an effort to provide an introduction to smart materials and systems. The authors make an attempt to present the material without assuming much prior disciplinary background. The aim of this book is to present adequate modeling details so that readers can appreciate the analysis involved in microsystems (and to some extent, smart systems) and thereby enabling them to get an in-depth understanding about simulation and design. Therefore, the book will also be useful to practicing researchers in all branches of science and engineering, who might be interested in applications where they can use this technology. The book presents adequate details of modeling of microsystems as well as addresses their fabrication and integration.  The engineering of practical applications of microsystems are areas for multidisciplinary research, already laden with myriad technological issues.  Evidently, books presently available do not address many of these aspects sufficiently well. We believe that this book gives a unified treatment of the necessary concepts under a single title.

                Anticipating the need for such a technology, the Institute of Smart Structures and Systems (ISSS), an Institute dedicated to promoting the field of smart materials and microsystems, was established. This Institute was not only instrumental in mounting a national program, triggering R&D activities in this field in India but also creating required human resource through training courses and workshops. Furthermore, ISSS also initiated a dialogue with Visvesveraya Technological University (VTU), Belgaum, Karnataka, a conglomerate of over 170 engineering colleges in Karnataka, for introducing a course at the undergraduate level in the area of microsystems and MEMS and for setting in motion drafting potential syllabus for the same. The culmination of this dialogue is this book. Material for this book has been taken from several advanced workshops and short courses conducted by the authors over last three years for faculty and students of VTU. A draft of the preliminary version of book was used by VTU colleges, where a course on microsystems was first introduced in 2009.  The current version is modified to incorporate feedback received from teachers of this course, who patiently used the previous draft to teach about 500 students from various colleges. In a sense this book has been class- and student-tested.

  This book has nine chapters covering various topics in microsystems and smart systems including sensors and actuators, microfabrication, modeling, finite element analysis, modeling and analysis of coupled systems which is of great importance in microsystems, electronics and control for microsystems, integration and packaging, and scaling effects in microsystems. The book also includes case studies on a few microsensor systems to illustrate the application aspects.

About the book

This book covers one of the most fundamental subjects of Engineering discipline – Strength of Materials, also known as Mechanics of Materials, Mechanics of Deformable Bodies or Mechanics of Solids globally. The subject lays the ground for various Engineering subjects, ranging from Machine Design, Finite-Element Analysis, Theory of Structures, Bio-Mechanics, and Fracture Mechanics.

In this book, the topics are broadly divided into two parts: Elementary Strength of Materials and Advanced Strength of Materials, thereby progressing from basic fundamentals to detailed analysis. The first eight chapters deal with basic concepts of strengths of materials such as theories of stress and strain, torsion, deflection and buckling of columns. The remaining chapters deal with the advanced topics such as advanced theories of stress and strain, energy principles, failure theories, theories of curved and continuous beams, unsymmetric or asymmetric bending.

Elementary Strength of Materials

In this part, we describe the fundamentals of the subject and have carefully included those topics which are generally taught in the various engineering disciplines ranging from Mechanical, Civil to Aeronautical, Chemical, Metallurgical engineering departments in their sophomore levels. Chapters 1–8 form a part of this level.

It may seem that the above package of topics covers mostly the course curriculum requirements of the undergraduate Strength of Materials generally followed by the various institutes for various engineering disciplines across the country. However, disciplines like Mechanical, Electrical, Aeronautical, Civil, Metallurgy may have some additional topics in their respective curriculum. For example, certain institutes have Analysis of Trusses also in their syllabus of Strength of Materials. However, we feel that it would be more justified and logical to include it in the course curriculum of Engineering Mechanics as has been the age-old practice and followed by the various engineering institutes. Consequently, we have not included this topic in our present work.

Advanced Strength of Materials

In this part, we have endeavoured to include those topics which require a slight maturity in the subject. Chapters 9–19 form a part of this level.

The topics are meant for more serious and matured reading of the subject. Some of these topics can be well-included in the undergraduate curriculum of the subject for those engineering disciplines like Mechanical, Aeronautical, Civil, Chemical and Metallurgy. Also, the authors believe that the coverage of the above topics will be useful for those students who are willing to study this subject in more advanced level.

Common Elements in the Two Parts

In both these levels we placed a common chapter – Stress–Strain analysis. This topic has been discussed from its fundamental level in the most elementary way and from the standpoint of more advanced tensorial theory. We sincerely believe that after going through this chapter a student wishing to pursue the subject in his/her engineering courses will have a modest introduction to the more advanced level subjects such as Theory of Elasticity, Theory of Stress and Deformation Analysis, etc. We have intentionally kept the topic of strain energy in the advanced level as we integrated many energy-related theorems along with it. This topic, we believe, shall certainly help students when they study Finite Element Methods or Matrix approach of Structural Analysis.

In both levels, all the chapters have quite a large number of numerical examples completely solved to bring out the intricacies of the relevant topics.

 

Bibliography and Appendices

At the end of the book, we have appended Bibliography section, where we have included a list of references. Also, we have compiled a set of appendices containing:
