Homework Help: Finding maximum possible load in an item

  1. Aug 28, 2012 #1
    How is the following question done?

    1. The problem statement, all variables and given/known data
    An offset link is connected to 2 cables like shown in the image attached.

    The offset link has a width 'w', of 200mm (or 0.2m) and a thickness of 35mm (or 0.035m). It has an allowable normal stress of 74 MPa.

    What is the maximum load that can be applied to the cables?

    2. Relevant equations

    Based on the values given, i'm assuming that the stress would need to be found.
    So... Stress = F/A is relevant.

    Not sure what other equations can be used

    3. The attempt at a solution

    I have no idea how to approach this question. A friend gave me a hint and said to first find the critical location of failing (no idea how to do that either!).

    In addition to the P/A axial stress, you also have bending stresses due to internal bending moments from the eccentric loading maximum about the centroidal axis of the link. What is that moment?
