Mechanical Engineering Principles

This book introduces the core principles of mechanical engineering in a clear, step-by-step manner. It covers topics such as static and dynamic loads, stress and strain, bending moments, torsion, and the fundamentals of machines and mechanisms. Each chapter presents theory alongside worked examples, helping students connect mathematical analysis to physical engineering situations. The authors place a strong emphasis on problem-solving methods commonly used in engineering design and maintenance. For students in Uganda, this textbook serves as a practical bridge between secondary school physics and the more specialized mechanical engineering courses they will encounter later. It is a useful companion for anyone studying introductory mechanics, strength of materials, or engineering dynamics.
