Q2. Figure shows a vertically loaded bracket attached to a fixed member by three identical bolts. Although the 20-kN load is normally applied in the center, the bolts are to be selected on the basis that the load eccentricity shown could occur. Because of safety considerations, SAE class 9.8 steel bolts and a minimum safety factor of 5 (based on proof strength) are to be used. Determine an appropriate bolt size and specify an appropriate tightening torque by assuming: (a) Tensile loading (FD 4FE), and (b) Shear loading (FD FE). |150 500 20 kN 20 kN 150 150 400 DE 100 Q2.
