A 2-m-long pin-ended column of square cross-section is to be made of wood. Assuming E = 13 GPa, σall = 12 MPa, and using a factor of safety of 2.5 in computing Euler's critical load for buckling, determine the size of the cross-section if the column is to safely support (a) a 120-kN load, (b) a 250-kN load. (c) Also determine the cross-section for allowable stress for a load of 300 kN.
