In today's modern world Machines play a vital role in ensuring that a series of many activities are running swiftly in day today's life of any human being. Kinematics of Machinery is one of the basic subjects in Mechanical Engineering which includes Knowledge of Machines and mechanisms and various tools and methods to analyse different kinds of mechanism. This course will introduce the learners to understand Basics of the kinematics which is one of the branches of mechanics along with other branches under mechanics and its hierarchy it also includes working of different mechanisms and its elements used in machines, concepts of rigid and resistance bodies. Learners will also be able to define Mechanism, Machine, structure and be able differentiate them. They will be able to define and differentiate Kinematic link, Types of links based on physical configuration of it and its numbers of nodes, Kinematic pair its type based on Based on nature of contact between elements, Based on relative motion between pairing elements and Based on relative motion between pairing elements.Kinematic chain Types of joints such as binary joint ternary joint and Quaternary joint in a kinematic pair is also included and The types of constrained motions like completely constrained motion incomplete constrained motion, successfully constrained motion.
