About the Course

In this course, you will be introduced to the fundamental principles and analytical modeling of fluid power components, circuits, and systems.

You will learn the benefits and limitations of fluid power compared with other power transmission technologies;  the operation, use, and symbols of common hydraulic components; how to formulate and analyze models of hydraulic components and circuits; and how to design and predict the performance of fluid power circuits.

This course is supported by the National Science Foundation Engineering Research Center for Compact and Efficient Fluid Power, and is endorsed by the National Fluid Power Association, the leading industry trade group in fluid power.
