Transformation of Stress (Mech. Materials)

  1. Jul 15, 2014 #1
    1. The problem statement, all variables and given/known data

    Question is attached

    2. Relevant equations

    σ(x) = 0
    σ(y)= P/A
    t(xy)= Tc/j

    3. The attempt at a solution
    I know how to do the stress transformation, but my only issue is noticing why σ(x)= 0, I cant see it, can someone help me.

    I assume that x is the thickness direction. Is that correct? If so, then the stress in the x direction is zero, because both surfaces of the pipe are in contact with the air (and the wall thickness is small compared to the lateral dimensions of the pipe).
