6. If ${\mathrm{F}}_2>{\mathrm{F}}_{\mathrm{allow},2}$, then the original assumption has been proved incorrect. In truth, member (2) controls the load capacity of the structure. Consequently, our earlier calculations must be corrected. This can be done in at least two ways:

a. Set ${\mathrm{F}}_2={\mathrm{F}}_{\mathrm{allow},2}$ and solve the equilbrium equations again for ${\mathrm{F}}_1$ and $\mathrm{P}$.

or alternatively,

b. Compute the ratio ${\mathrm{F}}_{\mathrm{allow},2}/{\mathrm{F}}_2$ and then multiply the values of ${\mathrm{F}}_1$, ${\mathrm{F}}_2$, and $\mathrm{P}$ by this ratio.
