A circular brass bar of diameter d is member AC in truss ABC which has load P= 5000 lb applied at joint C. Bar AC is composed of two segments brazed together on a plane pq making an angle α = 36° with the axis of the bar (see figure). The allowable stresses in the brass are 13,500 psi in tension and 6500 psi in shear. On the brazed joint, the allowable stresses are 6000 psi in tension and 3000 psi in shear. What is the tensile force NAC in bar AC? What is the minimum required diameter dmin of bar AC?
