2. A steel plate (Fig. Q.2) is riveted to a vertical pillar. The three rivets have a 15 mm diameter and carry the load and moment resulting from the external load of 8 kN. All length dimensions are in millimeters. The yield strengths of the materials are (Sy)rivet 600 MPa and (Sy)plate = 350 MPa. Calculate the safety factors for: = a. Shear of rivet when Ssy-0.57 Sy (10 pts) b. Bearing of rivet when σall 0.9 Sy (10 pts) c. Bearing of plate (10 pts) d. Bending of plate when σal-0.6 Sy (10 pts) State how failure should first occur. 8 kN 15-mm-diam bolts 15 :60. 30 DX 125 60 30+ 120- 400- Fig. Q.2 GOOD LUCK
