Question: A square wood column with side dimensions b (see figure) is constructed of a structural grade of southern pine for which Fc = 10.5 MPa

A square wood column with side dimensions b (see figure) is constructed of a structural grade of southern pine for which Fc = 10.5 MPa and E = 12 GPa. An axial force P = 200 kN acts on the column.
(a) If the dimension b =150 mm, what is the maximum allowable length Lmax of the column?
(b) If the length L = 4.0 m, what is the minimum required dimension bmin?
