Extracted text: 1. 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 legs back-to-back and separated by gusset plate whose thickness is 1 Imm. 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). Section 21 125 x 75 x 12 I.
