1. Design the pipe support with appropriate cross-section for this application. The signs and supporting truss span weight 300 pounds, and assume that the center of mass of the sign and supporting truss span is in the middle of the blue sign area as indicated to the right. The maximum wind loading in the y is 80 lb/ft2. The maximum allowable Von Mises stress using maximum distortion energy criterion is 20 ksi, which already incorporates a sufficient safety factor. Consideration of the weight of the steel pipe should be included in your analysis.
