Summary of the above video investigating sigma_x:

Click on probe and hover over the bar.

You will notice the middle of the bar has a uniform measurement, as indicated by hand calculations.

At the edge or boundary, stress readings are quite different. At the location where load is applied, there is a huge magnitude of stress and variance moving away. At the edge of the bar away from the load, the probe reads a very small value, converging to a value of 0. This follows our intuition of what boundary conditions are!

Using the probe may tell you the stress associated with a specific point on the bar.

 To view the less noticeable stress contours, click on the scale to edit. In this video, the orange (2nd highest value) was changed to 250 and the blue (2nd lowest value) was changed to 50. Notice how the The contour map changed to display the subtle difference in sigma_x.

In the video, we saw that ANSYS's values for sigma_x matches with:
