We will next look at Sigma-theta along the symmetry line. Click Solution > Sigma-theta without transiencealong symmetry in the outline window to bring up the stress distribution at the middle of the bar.

Looking at the distribution, we can see that the stress varies only as a function of r as expected. Also, we can see that there is a stress concentration in the area where the moment is applied. In the theory, this effect is ignored. In order to further examine the Sigma-r, let's look at the variation along the symmetry line. Click on Solution > Sigma-r without transiencealong symmetry. This solution is the normal stress in the r-direction at the midsection of the beam.
