Homework Help: Friction Effects in Metalworking

  1. Apr 27, 2015 #1
    1. The problem statement, all variables and given/known data

    Show how a constant interfacial shear stress mk < k decreases the forces required for uniaxial upsetting using mohr circles with decreasing m (<1). Assume a slab force balance.

    2. Relevant equations

    Mohr Circle Equations

    x/dx = 2mk/h

    σx + P = 2k

    3. The attempt at a solution

    Attached. What I have shows what the question asks but I'm not sure I did it right.
