Description

Starting with the fundamentals in this course, you’ll explore what machine mechanisms are and how kinematic links and joints come together to form kinematic chains. You’ll learn about degrees of freedom and how they determine the functionality of mechanisms. Through practical examples, the course highlights how these concepts are applied in real-world mechanical systems.A major part of the course focuses on velocity analysis using the Relative Velocity Method and the Instantaneous Centre (IC) Method, two essential techniques for studying motion in planar mechanisms. You’ll practice solving numerical problems to calculate velocities and accelerations at various points in mechanisms, preparing you to handle real-world challenges.You’ll also explore widely used mechanisms such as four-bar linkages, single slider-crank mechanisms, and double slider crank mechanisms, gaining insights into their operation and applications in industries like automotive, robotics, and manufacturing.This course is suitable for beginners, as all topics are explained clearly and gradually, with examples, diagrams, and problem-solving sessions. No prior experience in mechanical engineering is required, making it accessible to all learners. By the end of this course, you’ll develop a strong foundation in analyzing and designing mechanical systems. You’ll gain practical skills applicable in academia, technical industries, or personal projects, setting you on a path to master machine mechanisms and kinematics. Join now to unlock the mechanics behind motion and prepare for a rewarding career in mechanical engineering
