Lecture 1 An Introduction to Machines and Mechanisms

Dr. Ahmad PhD, PEng, Professor of Mechanical Engineering About this course: Welcome to the Machine Dynamics course, while a fun and easy course, an essential part of Mechanical and Manufacturing Engineering! We will introduce six key chapters that lay the groundwork for understanding mechanical systems. In Chapter 1, we'll start by exploring how mechanisms work, helping you see how things move in various machines. Moving on to Chapter 2, we'll talk about Degrees of Freedom, a concept that's all about understanding the possibilities and limitations within a machine motion. Chapter 3 introduces us to the Instant Center of Velocity, a crucial point in studying motion and kinetics. In Chapter 4, we'll focus on the Kinematics of Gears Train, breaking down the complexities of Simple, Parallel, and Planetary systems. The following chapters will cover Euler's Equation, Energy Method, and Gyroscopic Motion, aiming to make these topics approachable and practical. Throughout the course, we'll emphasize theory, problem-solving, and real-world applications, providing you with a solid foundation for your future endeavors in the exciting world of Mechanical and Manufacturing Engineering. In this lecture series, the topics will follow as: Lecture 1. An Introduction to Machines and Mechanisms Lecture 2. Degree of Freedom Lecture 3. Instant Center of Velocity - Part I Lecture 4. Instant Center of Velocity - Part II Problems Lecture 5. Gear Train - Part I - Introduction Lecture 6. Gear Train - Part II - Gears Geometry Lecture 7.
