Identifying stresses

  1. Apr 28, 2017 #1
    This isn't really a hard question, but it's been a while since I did this and I would just like to make absolute sure.

    This is an exceptionally simplistic draft of a wireblock (open at one side to allow for wire to be threaded over while each side of the wire is attached to the ballast). It's not meant to be pretty, not meant to be advanced or anything of the sorts. Personally I was vastly better at everything related to Processing, Gas, Energy and Petroleum and whatnot when it came to Mechanical Engineering, so structural design was never quite my field of expertise.. but I digress.

    Anyway, the point for me right now is to identify each stress. The pieces are meant to fit snuggly together and then welded. Assuming that the surface area of each "slot" that slides inside the openings of the other pieces is of adequate area to withstand the forces (it is designed to tolerate 5 times the designated load it would usually carry, for longevity purposes), and assume that the material is strong enough to resist the momentum bends.

    The thing I wonder is, would this design encounter shearstress? I know it would if the pieces were just flat and put "wall to wall" and welded together. But with the slots for them to slide into, would this not remove shear stress from the equation?

    Just take a look at the VERY basic paint-drawing I made. Ignore that it's clearly not evenly spread. Just imagine that the force down on the middle is directly below the force upwards.
