A 2-m-long pin-ended column with a square cross section is to be

A 2-m-long pin-ended column with a square cross section is to be made of wood. Assuming E = 13 GPa, oa = 12 MPa, and using a factor of safety of 2.5 to calculate Euler's critical load for buckling, determine the size of the cross section if the column is to safely support (a) a 100-kN load, (b) a 200-kN load.
