    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution
    Hello,

    I am wondering, is the area A in the equation meant to be the area of the empty space in the shaft, going all the way to the half way point of the structure (meaning, the area of the space included in the dotted lines in the diagram on my attempt?

    Yes, A is the area enclosed by the midline. As I said in your other problem, A is the average of the area to the outside surface and the area to the inside surface.

    Looks good. Your stress units should probably be in pascals.
