Sorry I have been MIA for a few days. Just wanted to thank everyone for their help with analyzing the stresses, as well as for all the extra information that I will be considering moving forward

Thanks so much for your help. To answer your question, there is an angled clip under the shaft to carry the vertical shear load. And the load is off set as well.

Are you saying that I need to analyse the reactions of the centroid of each bolt group, and then analyze how each of the bolts contribute to that reaction? As far as shear goes, the bolts will be handling the majority of the shear.

This is what I'm thinking. Each bolt provides a force in the same plane as the applied load, and each bolt provides moments that counteract the rotation of the shaft.

The beam that we have been discussing is more of a representation of an assembly of a few components. Due to the function of the assembly, I am not able to design it such that the bolts are attached on the top face.

Correct, no bolts on top

To expand on my thought process: I could use the current analysis methods I am using to analyze each face, but the supports from the other bolts not on the face currently being evaluated would have an affect on the face in question. Originally, I was considering treating the centroid of each...

As far as what I am doing to analyze each "face" of bolts, I am basically using the concepts outlined in this web page: http://www.roymech.co.uk/Useful_Tables/Screws/Bolted_Joint.html The bolts do not go through, they just screw into the beam itself, and they do not interfere with each other.

Yes, that is almost exactly right, except the bolts are only present on the side nearest us, the bottom of the beam, and the back face of the beam which butts up to the support plate. I tried to put arrows on your drawing to make it more clear

The bolts will be going through a fairly rigid structure of extruded aluminum framing, and the beam is also made of aluminum.

I am trying to analyze if the bolts in my design are sufficient to support the load on a shaft. Unfortunately, the bolts are not all located on one face, and though I know how to analyze each face by itself, but I would like to be able to combine them all into one problem. I have attached a...

I am trying to analyze the static stresses on a bronze bushing in a journal bearing if I was to use that journal bearing as a support for a cantilevered shaft. All the equations I have for contact stresses on the bushing suggest a uniformly distributed load across the entire bushing, which would...
