Question
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 8 mm in diameter. Assume a = 570 mm, b = 285 mm, h = 430 mm, and θ= 55°. If the normal stress in tie rod (1) cannot exceed 200 MPa and the shear stress in pin B cannot exceed 140 MPa, determine the maximum load Pmax that can be supported by the structure.
