1. Make a plot of the mesh.
2. Make a plot of the deformed shape. Include the undeformed shape in the same plot (this option is found by clicking on the "Edges" icon). Using this plot, discuss whether you have applied the boundary conditions correctly.
3. Compare the displacement at the right edge with a back-of-the-envelope estimate.
4. Make a plot of the Sigma_xx variation in the bar. Deduce the stress concentration factor for the hole on the right from this plot. Compare this to the theoretical value for a small hole in an infinite plate.
5. Determine how your stress concentration factor changes when you use a different mesh. Indicate the number of nodes and elements for your two meshes (this info can be found in "Details of mesh" by when expanding "Statistics"). Also, include a plot of your second mesh.
