EXAMPLE 1: Two possible configurations for assembly of a joint in a bridge are to be evaluated. The two configurations with the forces in the bridge members are shown in Fig.2. The radius of the pin is 1/2 inch. Determine which joint assembly is preferred by calculating the maximum shear stress in the pin for each case Configuration I Configuration 2 Nc 20 kips NB 15 kips Nr is kaps FIGURE 2
