Consider Determine the maximum axial load P the bar above can carry with a factor of safety of 2.5. It is .4 inches thick, 3 inches wide (w), the groove radius r is .5 inches, and the diameter d of the hole is .3 inches. The proportional limit of the material is 57 ksi.

You can download our ANSYS solution by clicking here. Load this Unzip the file and load the solution into ANSYS Workbench as in the tutorial. Please determine if this ANSYS solution Double-click on Results in Workbench to bring up the FEA results that have been calculated already. You might need to change the units for the results display by selecting Units > US Customary (in, lbm, lbf, F, s, V, A).

1. Look at the deformation plot. From this plot, what can you tell about the boundary conditions (displacement constraints and applied traction) that have been applied to this model?

2. Look at the sigma_xx plot. There are three distinct regions in this geometry:
a. Away from the hole and symmetric grooves
b. Adjacent to the symmetric grooves
c. Adjacent to the hole

Using paper-and-pencil calculations, please determine if the ANSYS solution for sigma_xx in each of these three regions is correct. If the solution is not right, use paper-and-pencil calculations to predict what the right values should look like. Justify your answer through quantitative reasoning.please indicate how it can be fixed. (Note that you don't need to fix it.)
