* Your answer is incorrect. Rigid bar ABC is supported by a pin at bracket A and by tie rod (1). Tie rod (1) has a diameter of 5 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 = 580 mm, b = 290 mm, h = 470 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 110 MPa, determine the maximum load Pmax that can be supported by the structure. D Answer: Pmax (1) a M 1.93 B b KN 2

*R9 4. Two A36 steel pipes, cach having a cross-sectional area of 200 mm, are screwed together using a union at B as shown. Originally the assembly is adjusted so that no load is an the pipe. If the union is then tightened so that its screw, having a lead of 0.55 mm, undergoes two full turns, determine the average normal stress developed in the pipe. Assume that the union at B and couplings at A and C are rigid. Neglect the size of the union. Note: The lead would cause the pipe, when unloaded, to shorten 055 mm when the union is rotated ane revolution. -09m- a6 m.
