I assume you were talking about this picture. The picture has nothing to do with how the rib is bent. In fact it has nothing to do with *<b>a rib</b>* at all but represents the entire assembly and its deflection characteristics under increasing load. The y axis represents crown and the x axis load. As the load increases the crown diminishes. The crown diminishes at a faster rate as the load is first added, but as the board stiffens with increasing load the rate of deflection per lb diminishes. That’s all. <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText><!--[if gte vml 1]><v:shapetype id="_x0000_t75" coordsize="21600,21600" o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f">
