Typically on a Street Light Pole there is an extended arm to which a Light Fixture is attched.
I am trying to analyse the stress & deflection on arm for various lengths, wall thickness of the extended arms. In this connections I am trying to list possible loads we acn apply on the 3D model of the arm. Here is a list I have come up with.
Do any of you guys think that I am missing some load?
Thanks

Depending on your location add weight of college students climbing to arm.

Both, this is one of the critical aspects of FEA, understanding what loads will be imposed on the item is the real world and making sure the FEA model sees the same loads.
Yep. Don't forget, your wind loads are going to go up DRAMATICALLY if you start hanging banners and such off the light.

I don't think any of this (in Inventor) is really going to give you useful information though (other than identify stress points).
Inventor only does linear static stress within relatively small displacements. Not facture (failure) analysis. I assume this assembly would bend well beyond elastic deformation before failure.
Below is a link for the implicit assumption for Inventor Stress Analysis.
If this is acceptable for your analysis, you may consider using Optimization to perform a linear static analysis that considers several design parameters/loadings.
Below is a quick demo video.

You may also consider using Autodesk Sim 360, since it supports buckling, and fatigue.

Good Luck!
Don't forget the Moment about the Light Fixture that will be inroduced to the Light Pole itself.
