This book is aimed to present the topics of Mechanical Engineering in a systematic, integrated and precise manner, primarily to meet the requirements of the aspirants of GATE (ME) and help them qualify the examination without unreasonable strain. The book is a self-explanatory and a fully-competent text for similar competitive examinations and undergraduate courses in mechanical engineering. The book helps to solve problems faced by aspirants in terms of extensive syllabus coverage, existing incongruity with syllabus, unavailability of a standard book, etc. Throughout the content, an intuitive and systematic approach is used to reinforce the fundamental concepts. The emphasis on fundamental concepts unveils inbuilt opportunities for developing the aptitude, which is the vital element for success in GATE.
About the Author
Ajay Kumar Tamrakar is currently serving Indian Railways as Senior Divisional Mechanical Engineer at Bhopal Division of West Central Railway, under the prestigious cadre of Indian Railway’s Services of Mechanical Engineers (IRSME). He received his B.E. (Mechanical Engineering) degree from Government Engineering College, Rewa in 2001. During his tenure at IISc, his research interests were smart materials, multi–functional composites, and multi-body dynamics and he presented several research papers in national and international conferences. Further, he qualified the Combined Engineering Services Examination (CESE) in 2002 based on which he served Central Electricity Authority (Ministry of Power) as Assistant Director. Later on, he qualified CESE again in 2005, and joined the IRSME in 2006.
Dinesh Kumar Harursampath is the Founder-Head, Nonlinear Multifunctional Composites Analysis & Design (NMCAD) Lab and has been an aerospace engineering faculty member at IISc, Bangalore since 2001. In addition to his vast teaching experience, he has guided about fifty post-graduate student theses. With over a hundred book chapters and articles in international journals and conference proceedings, his primary research interests are in geometric and material non-linearities as well as evolutionary interaction. He has pioneered multiple collaborative training, research and development projects with counterparts within India, USA, France, Italy and Canada. Collaborators include Boeing, Bell Helicopters, Ameron International, LM Glasfiber, DRDO, RWRDC, HAL, ARDB and DST. He is a Senior Member, AIAA, AeSI, ISSS.
