## Course description for academic year 2019/2020

### Contents and structure

In this course, students study the dynamics of gears, contact, rolling, inertial guidance systems, cranes on ships, and fundamental robotic systems. To accomplish this, this course introduces advanced mathematics in a distilled and controlled style. The course applies the math to the study of machines and mechanisms. This course also introduces students to the foundations of 3D graphics programming to visualize the motion of machines. Finally, this course introduces students to computational methods to prepare them for advanced work in mechanical engineering analysis. The skills in this class are basic to several to subjects at the Department of Machine and Marine Engineering, to an engineering career, and to life-long learning.
