Problem $6\mathrm{.}2.$C $($from text$)$

Given the following wood columns: Nominal Size: $88,$ Species: Douglas fir$-$larch, Grade: No

$,$ and unbraced length $=18ft.$

a$)$ Use the tables in Chapter $5$ to determine the allowable compression parallel to grain

$(F_c)$ and minimum modulus of elasticity $(E_{\text{m}\text{i}\text{n}}).$

b$)$ Compute the Euler buckling stress $(F_{cE}).$ Assume $E_{\text{m}\text{i}\text{n}}-E_{\text{m}\text{i}\text{n}\text{.}}.$

c$)$ Compute the column stability factor $($Cp$).$ This can be computed manually or using the

charts provided in Figure $6\mathrm{.}2.$ Either way required computing $\frac{F_{cE}}{F_c^{*}}.$

d$)$ Compute the allowable axial load $($P$)$
