Question 1: On a typical wooden hanging sign you have three pieces of beam. One main beam extends upwards from the ground and at the top a beam slices through this (so that on one side of the slicing beam there is more beam than the other) with the sign hanging down from the longer section. From the short section another beam (quite short) extends diagonally back down to the main beam. Why is the diagnal beam (could be chain) placed here rather than diagonally on the longer side (same side as the sign) ?
Question 2: If, instead of being used to hold up a sign, the beam structure was used to support an object which had been placed so it was sitting on the very end of the long section of the slicing beam why would the best place for a supporting arm be diagonally from the longer section to the main beam rather than from the shorter section to the main beam (the shorter section being the section on the other side of the main beam after the beam has sliced through the main beam)
