!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!Finally, we construct the actual solution of interest. We want to
!know what happens to the preload in the bolt, and the stress field around
!it, when the assembly temperature rises to 150 degrees F.
!Both the preload and the stresses increase because, for a uniform
!temperature rise, there is greater thermal expansion in the aluminum plates
!than in the steel bolt. Any method for applying preload that did not
!allow the load to change would be unable to predict this result.
