Free Body Diagrams Free Body Diagrams (FBDs).  A FBD refers to a process of isolating or “making free” a  particle from its surroundings.  It is  imperative  to begin any enforcement of equilibrium  with a FBD, as the FBD shows all the forces that act on the particle or body.
Procedure for drawing FBDs 1)  Decide on the particle whose equilibrium you want to analyze (you may be interested  in more than one).
