Comparing these two structural elements: Select one or more: a. The bending stress in the upper structural element is negligible compared to the bending stress in the lower structural element. b. The Axial stress in the upper structural element is more than a 100 times the bending stress in the lower structural element. c. The bending stresses in the lower structural element are about 35 times larger than the axial stresses in the upper structural element. d. The bending stress in the upper structural element is severe. e. The difference in the worst stress in each of the two elements is not significant.
