For 12' Roof Panel + 2' Overhang; Load Width = LW = 12' /2 + 2' O,H. = 8' ; Enter table on left at 8' read allowable span under required load: Thus for 100 M.P.H. wind loadllive load or 17 #/Sq. Ft. and Load Width = 8'-0" Maximum Beam Span for 2" x 4" x O,OSO" x 0.100" = I 11'-1" I Spans do not include length of knee brace, Add horizontal length of knee brace to above spans for total beam spans. ."Note: For small covers 2" x 2" beams may be used.
