The horizontal beam AB of 1.8-2 cross-sectional dimensions (b x h = 19 mm x 200 mm) is supported by the inclined support CD and is under the load of P = 12 kN at point B [see Fig. (a)]. The struts consisting of two rods, each 5b/8 in thickness, are connected to the beam by bolts penetrating the three rods at point C [see Fig. (b)]. (a) If the allowable shear stress of the bolt is 90 MPa, what is the minimum diameter dmin required for the bolt at point C? (b) If the allowable pressure stress of the bolt is 130 MPa, what is the minimum diameter dmin required for the bolt at point C?
