After completing today's reading, exercises, and the associated homework you should be able to:
Recognize when a system cannot be treated as a particle
"Remove" a support from a system and replace it with the appropriate reaction(s)- the force and/or moment components-by thinking about how the support restrains the motion of the system at the support location.
Recognize that reaction moments behave as couples
Draw complete and correct free body diagrams of systems by replacing supports with the appropriate reaction(s)
Draw a free body diagrams (FBDs) with all relevant forces and reaction moments on it
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.
