After completing today's reading, exercises, and the associated homework you should be able to:
Apply the equations of equilibrium (ΣF = 0) and ΣMpoint = 0) to a complete and correct FBD in order to determine unknown forces, moments, etc.
Identify two-force members in structures in order to make FBDs simpler
Draw several different FBDs for the same structure in order to complete equation sets for solving for unknown reactions
Draw FBDs and apply equilibrium to things that provide structural support (frames) and mechanisms that can move (machines) but aren't
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.
