A free-body diagram (FBD) of an object should show:
- The object isolated from its surroundings, with all external forces and reactions acting on it
- Only the internal stresses within the object
- The object together with all surrounding structures
- Only the applied loads, excluding support reactions
Answer
A. The object isolated from its surroundings, with all external forces and reactions acting on it
Solution
An FBD isolates the body of interest and replaces all supports and connections with the forces/reactions they exert on the body.
