Symphony of Motion
Learning Outcomes
Upon completing the Kinematics of Machines course, students can analyze, identify, and solve kinematic problems related to various mechanical components' position, velocity, and acceleration. They will also be able to design and optimize mechanical systems for desired motion characteristics, understand the operation of real-world machines, and utilize kinematic analysis tools.
