Problem 3.1: Six bolts are used to connect the steel member to the rigid support, as shown. The ultimate shear strength ($$\tau_u$$) of the bolts is 300 MPa. Determine the minimum bolt diameter required to support an applied force of P = 475 kN if a factor of safety FS = 4.0 is applied to the shear stress in the bolts. Answer: D = 25.923 mm Problem 3.2: The curved angle bracket ABD is supported at A by a single shear pin connection and at B by a tie rod (1) in double shear. The pins at B and C are each 0.75-in.-diameter pins, while the pin at A has a diameter of 1.25 in. The tie rod has a cross-sectional area of 1.50 $$in^2$$. The ultimate shear strength in each pin is 80 ksi, and the yield strength of the tie rod is 36 ksi. A force of 25 kips is applied as shown to the structure at D. Determine: (a) the normal stress in the tie rod (1). Answer: $$\sigma_1$$ = 26.76 ksi (b) the shearing stress in the pins at A and B. Answer: $$\tau_A$$ = 40.55 ksi, $$\tau_B$$ = 45.43 ksi (c) the factor of safety with respect to the yield strength for tie rod (1). Answer: $$FS_1$$ = 1.345 (d) the factor of safety with respect to the ultimate strength for the pins at A and B. Answer: $$FS_A$$ = 1.973, $$FS_B$$ = 1.761
