A roadway sign weighs 6.7 kN and is supported by a structural pipe that has an outside diameter of 185 mm and a wall thickness of 12.5 mm. The resultant force of the wind pressure acting on the sign is 12 kN, as shown. Assume a = 7.6 m, b = 5.5 m, Pā = 12 kN, and Py = 6.7 kN. (a) Determine the normal and shear stresses OH, Txy at point H. (b) Determine the normal and shear stresses OK, Tyzk at point K. Pāā y b Pā HK Answers: OH = TxyH = i OK = i Tyzk = i i MPa. MPa. MPa.
