A bracket is attached to a vertical column by means of six 200- identical rivets as shown in Figure 3. It is subjected to an eccentric force of 75 kN at a distance of 200 mm from the center of the column. The maximum permissible shear 20 75 stress for the rivets is 175 N/mm2. 75 Determine the centroid of rivet assembly. II. Determine the direct and resultant shear stresses T50--50- acting on each rivet. II. Which rivet is subjected to maximum shear force? Figure 3: Illustration for Question 4 (b). All What is the magnitude of maximum force? distances are in mm. IV. Determine the diameter of rivet. [12] ....
