After completing today's reading, exercises, and the associated homework you should be able to:
Explain the concepts of center of gravity, center of mass, and centroid, and give examples of how they are useful
State when center of gravity, center of mass and centroid are all the same
Give the criteria that a single-force acting at the center of gravity must meet in order to model a real system
Calculate centroids by integration
Find centroids of composite shapes from knowledge of simpler shapes that make up the composite shape
Note: Any term in bold is a key vocabulary term that you should be able to define, regardless of whether or not that is the specific learning objective.
