Fig. 9.1 The first sheet of the SLM spreadsheet

as described in the previous section. The values in the white cells are prescribed by
IEC 61400-2. The second chart, Fig. 9.2 , displays the parameters calculated from
the input information (Fig. 9.3 ).
The third chart labeled ''Loads from SLM'' contains the SLM loads with ref-
erence to the relevant equation in IEC 61400-2 1. The fourth chart, Fig. 9.4 , allows
the user to enter the extra information required to convert the SLM loads into
equivalent stresses. The fatigue data was taken from Peterson and Clausen [ 6 ] for
Hoop pine, a native Australian timber that grows well in plantation.
