This is a used book on the Theory of Machines, written in English. It covers a comprehensive range of topics, including: Introduction to Theory of Machines: Definitions, subdivisions, fundamental and derived units, systems of units (C.G.S., F.P.S., M.K.S., S.I.), presentation of units, rules for S.I. units, force, resultant force, scalars and vectors, and vector operations. Kinematics of Motion: Plane, rectilinear, and curvilinear motion; linear and angular displacement, velocity, and acceleration; equations of motion; graphical representations; and the relation between linear and angular motion. Kinetics of Motion: Newton’s laws of motion, mass and weight, momentum, force, moment of a force, couple, centripetal and centrifugal force, mass moment of inertia, angular momentum, torque, work, power, energy, conservation principles, impulse, impact, and collisions. Simple Harmonic Motion: Velocity and acceleration, differential equations, terms used, simple and compound pendulums, helical springs, center of percussion, and various suspension types. Simple Mechanisms: Kinematic links and pairs, structures, machines, constrained motions, kinematic chains, degrees of freedom, Kutzbach and Grubler’s criteria, inversions of mechanisms, and specific mechanisms like four-bar chains and slider-crank chains. Velocity in Mechanisms: Instantaneous center method, relative velocity method, velocities in mechanisms, rubbing velocity, and mechanical advantage. Acceleration in Mechanisms: Acceleration diagrams, Coriolis component of acceleration, and acceleration in slider-crank mechanisms. Mechanisms with Lower Pairs: Pantograph, straight-line mechanisms, steering gear mechanisms, and universal joints.

Belt, Rope, and Chain Drives: Selection, types, materials, velocity ratios, slip, creep, power transmission, tensions, V-belt drives, rope drives, and chain drives. Toothed Wheels: Friction wheels, advantages of gear drives, classification of toothed wheels, law of gearing, forms of teeth (cycloidal and involute), interference, helical gears, and spiral gears. Gear Trains: Simple, compound, reverted, and epicyclic gear trains, velocity ratios, and torques. Gyroscopic Couple and Precessional Motion: Precessional motion, gyroscopic couples and their effects on aeroplanes, naval ships, and vehicles. Inertia Forces in Reciprocating Parts: D-Alembert’s principle, velocity and acceleration of reciprocating parts, analytical and graphical methods for forces, and equivalent dynamical systems. Turning Moment Diagrams and Flywheel: Turning moment diagrams for various engines, fluctuation of energy, coefficient of fluctuation of energy and speed, and flywheel design. Steam Engine Valves and Reversing Gears: D-slide valves, piston slide valves, valve diagrams, Meyer’s expansion valve, and various link motions like Stephenson and Walschaert. Governors: Types, terms used, specific governors (Watt, Porter, Proell, Hartnell, etc.), sensitiveness, stability, isochronous governors, hunting, effort, power, and controlling force. Brakes and Dynamometers: Types of brakes and brake linings, braking of vehicles, types of dynamometers (absorption and transmission), and their classifications. Cams: Classification of followers and cams, terms used, displacement, velocity, and acceleration diagrams for different follower motions, and cam profile construction. Balancing of Rotating and Reciprocating Masses: Balancing of single and multiple masses, primary and secondary unbalanced forces, partial balancing, and balancing of various engine configurations. Longitudinal and Transverse Vibrations: Terms used, types of vibrations, natural frequencies, critical speeds, damping, and vibration isolation. Torsional Vibrations: Natural frequencies, effect of inertia, and torsional vibrations in multi-rotor systems and geared systems. Computer Aided Analysis and Synthesis of Mechanisms: Computer-aided analysis for four-bar and slider-crank mechanisms, synthesis of mechanisms, and programming techniques.

About the Author

R.S Khurmi: He was born on 29 Aug 1939 in Sunam, a small town in Punjab. He completed his schooling in Sunam and then he completed his professional studies from Phagwara and Delhi. He started his career in Punjab Irrigation Department as an Engineer. After guidance from Professor Das of Chandigarh Engineering College, Dr. Khurmi came to Delhi and took up Teaching and Writing Engineering Text Books as a full time career. He had a great respect for his Guru Shri B.L. Theraja, who introduced him to S. Chand and Company. His books got a good market, not only in India but also abroad. According to the survey of UNESCO, he is the leading and No. 1 author of Engineering textbooks in Asia. He wrote his first book when he was just 26 years old. People in teaching profession always referred that Khurmi has revolutionized the way of writing Engineering Text Books. He was one of the founder members in Executive Committee of Afro-Asia Book Council.
