Extracted text: 2. Both flanges of a universal column section member have 22 mm diameter holes arranged as shown in Figure (1). If the gross area of the section is 201x10 mm and the flange thickness is 25 mm. (a) Determine the net area Anet of the member which is effective in tension. (b) Determine the tension resistance of the tension member using steel S355.
