An assembly uses 22 M20x2.5 grade 8.8 bolts to join two structural members that are made of steel and are subjected to a total external load of 880 kN. The bolt grip /= 45 mm. Find: a) The external load per bolt. b) The joint constant, C. c) The torque required to tighten the bolt for reusable connection. d) The portion of external load taken by each bolt. e) The maximum and minimum bolt stresses. Use the following data: Sp=600 MPa, At=245 mm. For the steel members use A =0.78715, B = 0.62873, E = 207 GPa. 3.0 2.8 2.6 2.4 To 22 Did=2.0 2.0 1.8 1.33 1.6 1.2 1.09 1.4 1.2 10 0 0.05 0.10 0.15 0.20 0.25 0.30 r/d
