anonymous · Answer

Careful... a free-body diagram should only show forces acting ON the body, not forces exerted by the body on some other body. The key to forces is keeping straight who/what they are acting ON.

anonymous · Answer

Free body diagram shows all forces acting on the body - external ones and the ones coming from the constraints, points on the body by which it is connected with other bodies. Examples are: forces from pin joints, surfaces in a contact with a body etc.They come from the third law of dynamics.

FBD is actually a simple diagram to clearly show all the forces acting on a body
