Courses

      • MAE 3318-001 Kinematics and Dynamics of Machine

        This course teaches how to analyze motions (position, velocity, acceleration) of machine components within kinematic linkage using vector algebra and modern engineering tool. The course also teaches how to synthesize specific kinematic linkage to achieve certain prescribed motion. The course also covers cam design principle and force analysis on the kinematic joints within a linkage when the linkage is under certain motion.
