The book is designed to provide basic understanding of the principle of mechanical engineering for foundation and mid-level engineering and technology student and also provide a comprehensive and coherent teaching and training material for students of mechanical engineering technology in the tertiary education system.The text consists of eight chapters. The first four chapters are on statics while the last four chapters are on dynamics. Each chapter contains sufficient worked examples and exercises, which are carefully prepared to make reading and understanding easy and enjoyable.It is also hoped that all students, instructors, and lecturers of mechanical engineering would find this book beneficial for their academic and professional development.
