    3. The attempt at a solution
    can someone help me determine the internal forces I need to work out the stresses for part A?

    You almost have it. From an overall force balance, how is F1 related to Pc? Once you establish this, substitute it into the equations you have already developed. This will give you all the rest of the forces.
