Multiple choice

Two equal angles ISA 100 mm x 100 mm of thickness 10 mm are placed back-to-back and connected to the either side of a gusset plate through a single row of 16 mm diameter rivets in double shear. The effective areas of the connected and unconnected legs of each of these angles are 775 mm2 and 950 mm2, respectively. If these angles are NOT tackriveted, the net effective area of this pair of angles is

  1. 3650 mm2

  2. 3450 mm2

  3. 3076 mm2

  4. 2899 mm2
