About the Book

Tapping the energies of nature, building machines and transportation are important mechanical engineering activities required to meet diverse needs of mankind. That is why every engineer, whatever, may be its branch, has to have basic knowledge in Mechanical Engineering. To meet this requirement, all the universities in India/ abroad prescribe a core course in principle of mechanical Engineering. This course forms a core subject which is taught to first year students of all disciplines of engineering in all technical institutions. The text and literature, contains a collection of valuable ideas/ views, is the outcome of the distillation of the available text books written by distinguished authors.

Based on our teaching experience of this subject, we have endeavoured to present a systematic and logical explanation of basic concept of mechanical engineering. A large number of solved problems and objective type questions are included in order to make the underlying principles.

Salient features of this Book

•        This book covers syllabus of most of the universities and engineering colleges.

•        A larger number of problems have been taken from most of the leading resources.

•        At the end of each chapter a number of numerical questions with answers are given.

•        Precise and logical presentation of the basic concept and principles is followed.

•        Text written in simple, lucid and easily understandable language.

•        Useful for GATE, AMIE and Engineering service examination.

•        Consistent use of S.I units and notation throughout the text.

•        An Attempts to present the subject in an interactive manner.

Through the text, attempt has been made to present subject matter in a very simple, lucid and precise manner, keeping in view student’s difficulty in solving numerical problems.

Coverage of this Book

The present book is designed into 15 chapters. Chapter 1 describes non-conventional energy and their resources like solar energy, wind energy, tidal energy, ocean thermal energy, geothermal energy, nuclear energy, and magneto hydrodynamic energy. We also introduce the basic concepts of hydroelectric power plant and nuclear power plant with some of the non-renewable energy sources. Chapter 2 covers the law of thermodynamics and concept of entropy. Under the law of thermodynamics, we discuss about zeroth, first, second and third laws of thermodynamics, concept of specific law, Gay Lussac’s law, combined gas and constant etc.

Chapter 3 covers steam properties and its generation; various properties of steam such as internal energy, enthalpy and entropy at different ambient conditions are discussed. We introduce the steam table and the Mollier diagram that are helpful in showing the methods to find the properties of steam at the given condition. In addition to this, we introduce the working of steam generator (boilers) and the functions of various mountings and accessories used in boilers. Chapter 4 describes working principle of steam turbines and classification. We also discuss the function of condenser and its types in this chapter.

Chapter 5 deals with internal combustion engines and their working. There is a wide scope to discuss about various mechanisms and developments in I.C engines, but we have focused our discussion only on the basic concept of working of I.C engines such as petrol (gasoline) engines, diesel engines, two stroke engines, four stroke engines and performance measurement of an I.C engines. We have tried to explain the basic of cooling and lubrication system in brief in this chapter. Chapter 6 introduces the basic concepts of different refrigeration cycles, including vapour compression and absorption refrigeration. We also discuss psychometric properties of atmospheric air and develop various psychometric relations with adequate numerical examples. Some numericals are solved with the help of psycho metric chart.

Chapter 7 deals with the various modes of heat transfer i.e. conduction, convection and radiation. It gives a basic idea about the thermal conductivity, thermal resistance and the overall heat transfer coefficient. Chapter 8 covers hydraulic machines. Hydraulic machines deals with the work ing of water turbines, water pumps along with its constructional details. Chapter 9 demonstrates the various forces acting upon the body and also explains the fundamental law of mechanics and Coulomb’s Law of Friction. We also discuss the analysis of truss by both Methods of Joints and Methods of Sections with numerical example.

Chapter 10 discusses the kinematics of a body and rotation of rigid bodies. It also explains physical meaning of instantaneous center of rotation and explains analytical and graphical method for determining the relative velocity. Chapter 11 explains the kinetics of a rigid body and D’Alembert principle. It covers Work Energy Principle, Principle of Impulse and Momentum and also Law of Conservation of Momentum. This chapter demonstrates the kinetics of rotary motion with practical example. Chapter 12 describes stress and strain, that is, the properties of materials under various types of loading. It also demonstrates relationships among different types of elastic constants. This chapter gives the concept of sharing forces and bending moments in beams.

Chapter 13 deals with lifting machines and their working. The Law of Machines, mechanical advantage, velocity ratio and efficiency of different types of lifting machines, such as wheel, single and double purchase winch crab, screw jack etc are discussed. Chapter 14 deals with power transmission devices such as belt drive, chain drive, and gear drive. In belt drive, we discuss about open and cross belt drive and their applications; in chain drive and in gear drive, we discuss about different types of gears and working of gear trains. Chapter 15 covers important types of vibration system experienced in daily life. This chapter provides numerical solution of various vibratory systems.

We are indebted to various authors whose books we have consulted in writing of this book and lastly we would appreciate suggestions, criticism, if any, received from readers (rpsharmabit123@gmail.com or j.chikesh123@gmail.com).
