Mechanical Eeering, Mechanisms, Degrees of Freedom, Four-bar mechanism, Slider Crank mechanism, Inversions What you'll learn Basics of machines, mechanisms, kinematic links and joints Mobility of a Mechanism and Calculating the Degrees of Freedom Inversions of a Four-bar Chain and Grashof' s Law Inversions of a single slider crank chain - Quick Return Motion Mechanisms, Rotary and Oscillating Cylinder Ee, Hand-Pump Inversions of a double slider crank chain - Elliptical Trammel, Scotch Yoke and Oldham Coupling Requirements No prior knowledge is required. Everything will be taught starting with the required basic knowledge Description Kinematics of Machines is an important subject for people aspiring to be mechanical eeers and discusses about the relative motion of various elements in a machine. The subject also describes how the structural design of a mechanical system can be optimized to produce a desired motion of its elements and achieve better performance. Kinematics of machines has great practical applications in designing machines used in different industries such as manufacturing, textile, mining and aerospace etc. The present course (Kinematics of Machines - Part I) covers only the first module discussed in the course-overview video and has been designed to introduce the subject basics to the learners. The course material has been described systematically supported with properly curated video lectures, PDF lecture notes and quizzes. The concepts in the course have been elaborated using real life applications, animations of machine elements and schematics diagrams and solved numerical problems.Topics that will be covered in the course are listed as follows: 1. Kinematics, Machine, Mechanism, Kinematic links and Kinematic pairs, 2. Mobility of a Mechanism, Computation of Degrees of Freedom, Kutzbach and Grubler Criteria, Solved Numerical Problems, 3. Four-bar chain and its inversions, Grashof Law, Coupled wheels of a locomotive, Beam Ee, Watt's straight line mechanism, Ackermann Steering Mechanism, 4. Slider Crank Chain and its inversions, Rotary Ee, Whitworth Quick Return Motion Mechanism, Oscillating cylinder ee, Crank and slotted lever mechanism and Hand-pump mechanism, Solved Numerical Problems, 5. Double Slider-Crank Chain, Elliptical trammel, Scotch Yoke mechanism, Oldham Coupling.Course material that will be provided to the learners include, 1. Pre-recorded video lectures, 2. Lecture PDF files, 3. Quizzes in between the lecture sessions.
