Rigid bar ABC is supported by a pin at bracket A and by tie rod (1). Tie rod (1) has a diameter of 6 mm, and it is supported by double- shear pin connections at B and D. The pin at bracket A is a single-shear connection. The pin at B is 6 mm in diameter. Assume a = 600 mm, b = 300 mm, h = 350 mm, and 0= 65°. If the normal stress in tie rod (1) cannot exceed 180 MPa and the shear stress in pin B cannot exceed 140 MPa, determine the maximum load Pmax that can be supported by the structure. Answer: Pmax (1) a i B kN
