An introduction to the methodology of the modeling will be introduced and students will need to integrate these concepts to different concepts covered in previous courses by applying them to real systems to increasing complexity in the following areas: mechanical, hydraulic, thermal, electrical.
Analogies can be made between electrical, hydraulic, thermal or mechanical. Act normal.
