The structural support structure must lift the pipeline above the ground to allow free passage of wildlife under the pipeline. The loading on each truss support must be determined by calculating the weight of oil and of the pipe over each support. Assume that supports are spaced 2 meters apart and thus each truss is holding up 2 meters of pipeline. Each support is a simple truss in the shape of an equilateral triangle. Thus the angle between members is 60o. You will need to find the stress in each member due to the weight of the oil and the pipe.
