Rigid bar ABC is supported by a pin at bracket A and by tie rod (1). Tie rod (1) has a diameter of 7 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 5 mm in diameter. Assume a = 640 mm, b = 320 mm, h = 360 mm, and 0= 70°. If the normal stress in tie rod (1) cannot exceed 210 MPa and the shear stress in pin B cannot exceed 100 MPa, determine the maximum load Pmax that can be supported by the structure.

Question
Rigid bar ABC is supported by a pin at bracket A and by tie rod (1). Tie rod (1) has a diameter of 7 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 5 mm in diameter. Assume a = 640
mm, b = 320 mm. h = 360 mm, and 0= 70% If the normal stress in tie rod (1) cannot exceed 210 MPa and the shear stress in pin B cannot
exceed 100 MPa, determine the maximum load max that can be supported by the structure.
