A column 3m long and pinned at both ends carries an axial load of 190 KN. The column is made up of two-angles of unequal legs with long legn back-to-back and separated by gusset plate whose thickness is 11mm. Use A50 steel with Fy=248 MPa, Fu-415 MPa and E-200 GPa. Three sections are being considered, as follows, with their respective properties relative to this problem (all units are in meters).
