34.23.- In the "Variables" section enter a range between 0.250" and 0.325" for the

dimension. In the "Constraints" area, select "Factor of Safety" and "is greater than"

and enter 1.5. In the "Goals" section select "Mass" and "Minimize" to optimize for

the lightest part that meets a factor of safety of at least 1.5. When finished click

Run to optimize the model.

After running the optimization, we can see the "Results View" with the

initial value and the optimal value. Selecting a column will update the model with

those values.

For optimization to work, we need to have a study with a factor of safety

higher than what we need, basically over designed. If the study has a high

factor of safety, we can optimize the model to make the part lighter, and still

have a factor of safety that meets our design requirements.
