The case of load A represents the wind hypothesis (C.S.=1.5), application of a transversal load, F, combined with the vertical load, V.
The case of load B, depending on the use of the cross-bar, may represent the “traction imbalance” hypothesis (C.S.=1.2) or that of end of line (C.S.=1.5), depending on the case, the following loads will apply: longitudinal, L, transversal F and vertical, V.
