2D Kinematics of Rigid Bodies - Engineering Mechanics (Undergraduate Advanced)

In this course, you will learn the fundamentals of two-dimensional kinematics of rigid bodies, which is the branch of mechanics that deals with the geometry of the motion of rigid bodies without considering the forces that cause it. You will learn how to use different coordinate systems and reference frames to express the position, velocity, and acceleration of various points on a rigid body in plane motion. Empower yourself with the knowledge and skills needed to excel in diverse fields such as mechanical engineering, robotics, aerospace engineering, and beyond. Imagine designing a robotic arm that moves with precision, or optimizing the performance of a rotating machinery. These are some of the countless applications of rigid-body kinematics you will learn in this course. By the end of this course, you will be able to: - Understand the rotation of rigid bodies about fixed axes and its applications - Analyze absolute motion to understand how rigid bodies move through space - Explore relative velocity analysis to solve complex motion problems - Master the concept of instantaneous centres of rotation for precise motion analysis - Understand relative acceleration analysis to predict the behavior of moving bodies - Analyze motion relative to a rotating frame to unravel the dynamics of rotating systems Whether you're a seasoned professional looking to expand your knowledge or a curious beginner eager to explore the motion of rigid bodies, this course is for you. Once enrolled, you have access to dynamic video lessons, interactive quizzes, and live chat support for an immersive learning experience.
