Sign criteria for momentum in beams is:
Diagram is drawn in the plane X'Z' and in the side of the beam where the traction is. Positive values of the momentum mean that traction is in the –Z' side (in the negative side of Z').
Other strengths in beams are described in the Analysis of a beam structure chapter.
