Foundations of Theory of Machines: Kinematics and Mechanisms

Understanding how machines move and transfer force is the cornerstone of mechanical engineering. Whether you are preparing for competitive engineering exams or building a foundation for machine design, mastering kinematics is essential. This text-based course guides you through the core principles of the Theory of Machines. You will start with the absolute basics—defining links, kinematic pairs, and mechanisms—before progressing to analytical methods used in modern engineering workflows. What you'll learn: Understand the fundamental definitions of links, kinematic pairs, and chains; Calculate the degree of freedom for various planar mechanisms using Grubler's criterion; Analyze inversions of four-bar chains and slider-crank mechanisms; Apply analytical methods to determine velocity and acceleration in simple mechanisms; Practice solving typical exam-style problems with step-by-step written explanations; Explore how classic kinematic theories integrate with modern computer-aided simulation tools. The course begins with foundational terminology and structural analysis of mechanisms, then transitions into kinematic analysis. Through clear written explanations and structured practice problems, you will develop an intuitive grasp of machine dynamics. This course is designed for beginner mechanical engineering students, self-taught designers, and exam aspirants, with no prior advanced knowledge of machine dynamics required.
