A roadway sign weighs 7.6 kN and is supported by a structural pipe that has an outside diameter of 270 mm and a wall thickness of 9.5 mm. The resultant force of the wind pressure acting on the sign is 12 kN, as shown. Assume a = 7.8 m, b = 4.7 m, P₂= 12 kN, and Py = 7.6 kN. (a) Determine the normal and shear stresses OH, TH at point H. (b) Determine the normal and shear stresses OK, TK at point K. y b HK Answers: OH = TxyH = Ok = Tyzk = i i i i MPa. MPa. MPa. MPa.
