The book in its fifty-fifth edition provides all aspects and detailed study of Engineering Graphics or Engineering Drawing ? Plane and Solid Geometry, a core subject for all branches of Engineering study, presented in a lucid manner and easy-to-follow style. The text-book follows the first-angle method of orthographic projection, however, the third-angle projection method has not been completely ignored. The entire book is printed in two colour which enhance the utility of the book. The subject matter has been arranged in 26 chapters such as Drawing Instruments and Their Uses Sheet Layout and Free-Hand Sketching Lines, Lettering and Dimensioning Scales Geometrical Construction Curves Used in Engineering Practice Loci of Points Orthographic Projection Projections of Points Projections of Straight Lines Projections on Auxiliary Planes Projections of Planes Projections of Solids Sections of Solids Development of Surfaces Intersection of Surfaces Isometric Projection Oblique Projection Perspective Projection Orthographic Reading and Conversion of Views Centres of Gravity and Moments of Inertia of Areas Nomography Screw Threads Screwed Fastenings Riveted Joints and Welded Joints Computer Aided Drafting (CADr). Chapter 26 on Computer Aided Drafting (CADr) is entirely rewritten with inclusion of 50 self-interactive and self-learning practice modules. As a novel pedagogical concept, 51 audiovisual animation modules are presented through web-portal for better visualization and understanding of the subject. The solutions to exercises of Chapter 17, Isometric Projection and Chapter 20 Conversion of Views are given in this edition. The topics of the subject are covered in 26 well-arranged chapters ? therein it now contains: * 1617 Self-explanatory and neatly drawn diagrams * ?523 Worked examples (Problems) * ?900 Exercises at the end of chapters * ??34 Useful tables The book covers the syllabi in Engineering Drawing or Engineering Graphics as a core subject for Degree Examinations of all the Indian Universities, Diploma Examinations conducted by various Boards of Technical Education, Certificate Courses, I.T.I. as well as for the A.M.I.E., U.P.S.C., G.A.T.E., I.E.S. and other similar competitive and professional examinations. It should also prove of interest to the practising professionals.
