The bolted joint given in the figure is being applied on by the load P which is fluctuating between 0 and 2x10* N. Both of the clamped parts are made of steel (E = 207 GPa). The bolt is M12x1.75, IsO 9.8 grade, which is tightened to 75% of the proof load. The dimensions are given as d = 12 mm, 4 = 20 mm, l2 = 30 mm, and the length of the bolt is L = 75 mm. Find a. The factor of safety against fatigue failure using the Goodman criterion. b. The factor of safety against separation. c. The factor of safety against yielding. P/2 P/2 L = 20 mm 12= 30 mm P/2 P/2 e D- The bolted joint given in the figure is being applied on by the load P which is fluctuating between 0 and 2x10* N.
