- From the above analysis one can conclude that Cast Iron & Cast Bronze tensile stress is very less compaired to Cast steel.
- hence, from material selection point of view I would select Cast Steel.
- Also, the Tensile stress limit is very clost to actual results, i would also suggest to increase the thickness of the gears to provide more contact area to reduce the stress level further down.
