Homework Help: Interference Fit Problem involving changing deltas.

  1. Nov 15, 2012 #1
    1. The problem statement, all variables and given/known data

    Problem number 3 is the one I have the issue with. I attached it as a PDF file.

    2. Relevant equations

    Looking through my textbook, the equations that I think are relevant are:
    I am assuming the hub and the pipe are the same material
    σ=p((c^2+b^2)/(c^2-b^2)) this is for the tensile at the inner surface in the tangential direction

    I understand the cyclic loading part, I just don't follow what to do with the two interferences.

    3. The attempt at a solution

    I feel I would be able to work out a solution to this problem if I knew the right direction to go in. I know how to handle interference fits, but I do not know if this problem is solvable without the thickness of the pipe.
