Free-Body Diagram Summary
+
A free-body diagram isolates a body and illustrates all the forces that act on the body
so that a complete and accurate account of all of those forces may be considered.
+
Four steps must be performed to construct a free-body diagram:
-
Determine the body or combination of bodies to be isolated.
-
Isolate the body or combination of bodies with a diagram that represents the
complete external boundaries.
-
Represent all forces that act on the isolated body in their proper positions
within the diagram.
-
Indicate the choice of coordinate axes directly on the diagram.
Summary
The concept of the free-body diagram is summarized below.
