This page contains the findings for conducting FEA on the steering arm.
...
Vy = 1054.575 N
Mx = 54.8379 N⋅m
My = 147.6405 N⋅m
Mz = 173.5619535 N⋅m

| 11/04/19 | | | - FEA SEEMS TO BE LINING UP WITH MY CALCS! In the right range!
- Sharp corners are likely to have the highest stresses. This was also observed by fixing the hole surface of the rod end hole; the pointed edge of the hole had the highest stress in that case.
- Filleting seems to be good
- Bend doesn’t affect it a lot
- The mesh doesn’t need to be crazy small
- It’s okay if it’s not like the previous steering arm, since our loading case is different
| - Why are our loading conditions so different from MSXII’s?
- What happens when you make it thinner and taller? This increases moment of inertia; is it better for torsion? Test this tomorrow
- How does it work without any fillets? Test this tomorrow

| - Making the arm thinner was an okay idea
- Refining mesh made results more predictable
- Filleting isn't crucial
- Our culprit is not the rod end hole, but the steering bracket hole
| - Can we add weight reduction slots? Is it better on the top, bottom, left, or right sides?
- Should the wall thickness change around the steering bracket hole? Maybe the shape shouldn't be so rectangular there? Look into other shapes.
