Problem 1.8-4 Two bars of rectangular cross section (thickness t 5 15 mm) are connected by a bolt in the manner shown in the figure. The allowable shear stress in the bolt is 90 MPa and the allowable bearing stress between the bolt and the bars is 150 MPa. If the tensile load P 5 31 kN, what is the minimum required diameter d min of the bolt? 50 CHAPTER 1 Tension, Compression, and Shear P P P t P t Solution 1.8-4 Bolted connection One bolt in double shear. P 5 31kN t allow 5 90MPa ± b 5 150MPa t 5 15mm
