help is limited from tutor online, all they said was compare images with others. no data, simulation tools, info on what these images show or anything was given. I dont know what they are showing the images can you help. I guessed they all showed stress but not sure and cant find image a close enough image for the Truss Bridge.
For the fixed end points at ends of the truss, would there be 1st point of failure instead of middle. i guess becuase compression or fatigue.
