For 12' Roof Panel + 2' Overhang; Load Width = LW = 12' 12 + 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 #I~d Width = 8'-0" Maximum Beam Span for 2" x 4" x 0.038" x 0.100" = 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.
