After completing today's reading, exercises, and the associated homework you should be able to:
Recognize when friction forces are acting on a surface and draw them in the correct direction on an FBD
Recognize when friction forces can be replaced by μsN, μkN, or neither one
Apply equilibrium to systems subject to friction forces
Draw FBDs for systems for which motion is impending, either by slipping or tipping
Use equations of equilibrium to solve for unknown forces, moments, etc. for systems for which motion is impending
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.
