For the fixture shown in Figure P15–28, the inside surfaces of the eight holes are increased in temperature by 80 ° F. Determine the von Mises stresses throughout the fixture. What is the largest von Mises stress in the fixture? Is there concern for failure due to yielding of the material? Assume the material is aluminum alloy 6061-O (annealed). Fix the inside surface of the upper hole.
