Engineering Science, Second Edition provides a comprehensive discussion of the fundamental concepts in engineering. The book is comprised of 16 chapters that provide the theories and applications of different engineering concepts. The coverage of the text includes statics (equilibrium and structures), dynamics (motions and vibrations), and energy and thermal systems. The book also discusses electrical circuits, including direct and alternating current circuits, and electric and magnetic fields, including electromagnetism. The text will be useful to students of the various branches of engineering, such as mechanical, electrical, and civil.

Former Lecturer at Buckingham Chilterns University College, High Wycombe, UK, and now retired, William Bolton has worked in industry and academia as a senior lecturer in a college of technology, a member of the Nuffield Advanced Physics team, an adviser to a British government aid project in Brazil on technical education, as a UNESCO consultant in Argentina and Thailand, and as Head of Research and Development at the Business and Technician Education Council. He has written many engineering textbooks, including Mechatronics, 4th ed., Engineering Science, 5th ed., Higher Engineering Science, 2nd ed., Mechanical Science, 3rd ed., and Instrumentation and Control Systems.
