A square wood column with side dimensions b (see figure) is constructed of a structural grade of spruce for which Fc = 900 psi and E = 1,500,000 psi. An axial force P = 8.0 k acts on the column.
(a) If the dimension b = 3.5 in., what is the maximum allowable length Lmax of the column?
(b) If the length L = 10 ft, what is the minimum required dimension bmin?
