Study section 1 and section 3 of the aaashto standards. section 3 gives details for determining wind and ice loads. b) both sections of your support structure will be made of identical hollow-cylinders (tubes) having an inner diameter of 6 inches. c) the single traffic light weighs 30 pounds and may be treated as a box that is 30 inches tall by 10 inches wide by 6 inches deep. d) the single sign weighs 80 pounds and is 6 feet tall and 6 feet wide. e) both sections are made from a36 steel that has maximum allowable shear stress of . (a factor of safety of 3.0 has already been applied)allow100mpaf) determine the minimum outer diameters for the pole and the mast arm. use the maximum shear stress theory of failure. assume that the weight, wind, and ice loads will all occur simultaneously. consider static failure only (ignore fatigue for now). g) your design report will describe in detail your calculation of all loads, calculation of all stresses, and your process for the determining the correct size for the structural tubes.
