• Understand how to add vectors
  • Use a free body diagram to list out all of the forces in each dirrection.
  • Determine if a given force, in a given direction, is positive or negative, with respect to your axis choice.
  • Use the angles on the FBD to express the components of forces as a magnitude times sine or cosine.
  • Be able to identify, from a well scaled FBD, when a system is in equilbrium
