Introduction to Theory of Machines: Kinematics and Mechanisms

Understanding how physical parts move and interact is the cornerstone of mechanical engineering design. This text-based course breaks down the core principles of the Theory of Machines, helping you build a rock-solid foundation in kinematics. You will transition from basic physical concepts to confidently analyzing complex mechanical linkages, calculating mobility, and understanding how real-world machines transmit motion. What you'll learn: - Understand the fundamental definitions of links, kinematic pairs, and kinematic chains. - Calculate the degrees of freedom and mobility of planar mechanisms using Kutzbach and Grübler criteria. - Analyze classic mechanisms, including four-bar linkages, slider-crank chains, and their practical inversions. - Determine velocity and acceleration in mechanisms using step-by-step analytical methods. - Explore how modern computer-aided engineering (CAE) tools apply these kinematic principles in digital simulations. The course begins with core terminology and foundational definitions, guiding you step-by-step through joint classifications, mobility equations, and the practical application of linkage inversions. Through clear written explanations and structured practice problems, you will master the analytical techniques used by professional engineers. This course is designed for mechanical engineering students, self-taught designers, and anyone preparing for technical engineering assessments. No advanced prior knowledge of machine design is required. Start reading today to unlock the mechanics behind everyday machines.
