520 _a"Mechanical Engineering Principles offers a student-friendly introduction to core engineering topics that does not assume any previous background in engineering studies, and as such can act as a core textbook for several engineering courses. Bird and Ross introduce mechanical principles and technology through examples and applications rather than theory. This approach enables students to develop a sound understanding of the engineering principles and their use in practice. Theoretical concepts are supported by over 600 problems and 400 worked answers.The new edition will match up to the latest BTEC National specifications and can also be used on mechanical engineering courses from Levels 2 to 4"--

520 _a"In this book John Bird and Carl Ross introduce mechanical principles and technology through examples and applications - enabling students to develop a sound understanding of the principles needed by professional engineers and technicians. No previous background in engineering is assumed and theoretical concepts are supported by over 600 problems and worked examples. This completely new text is designed to match a wide range of pre-degree courses, and provide an accessible introduction for undergraduates with no previous background in engineering studies. The authors have ensured syllabus-match for the leading UK courses at this level: AVCE optional units Mechanical Engineering Principles and Further Mechanical Engineering Principles, and the new BTEC National unit: Mechanical Principles"--
