Description

Kinematics of Machines is an important subject for people aspiring to be mechanical engineers 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) covers the Module I & II discussed in the course-overview video. 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, mechanism animations, schematics diagrams and solved numerical problems.

Topics that will be covered in the course are listed as follows:

Module I - 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 Engine, Watt's straight line mechanism, Ackermann Steering Mechanism, 4. Slider Crank Chain and its inversions, Rotary Engine, Whitworth Quick Return Motion Mechanism, Oscillating cylinder engine, Crank and slotted lever mechanism and Hand-pump mechanism, Solved Numerical Problems, 5. Double Slider-Crank Chain, Elliptical trammel, Scotch Yoke mechanism, Oldham Coupling.

Module II - 1. Velocity Analysis in Mechanisms by Relative Velocity Vector (Graphical) Approach 2. Velocity Analysis in Mechanisms by Instantaneous Centre of Rotation (Graphical) Approach 3. Acceleration Analysis in Mechanisms (Graphical Approach) 4. Velocity and Acceleration Analysis in Mechanisms - Analytical Approach.

Module III - will be updated soon

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.
