The design оf а white оаk [E = 12.4 GPа, σPL = 30 MPa] cоlumn of square cross section has the following requirements. It must be 6.0 m long, it must have pinned ends, and it must support an axial load of 90 kN with a factor of safety of 2.0 against buckling. Determine the required width of the cross section.
