                                     Select the Total option, the Total  Deformation item will
                                     pop-up beneath the Solution item. Right click at the Total
                                     Deformation  item  and  select  Evaluate  All  Results,  the
                                     solution in form of color fringe plot will appear as shown in
                                     the figure.
                                    Click the Solution item, the Stress tab will appear on the
                                     lower  menu  bar.    Click  on  this  Stress  tab  and  Select  the
                                     Equivalent  (von-Mises)  option,  the  Equivalent  Stress
                                     item will pop-up beneath the Solution item. Right click at
                                     the  Equivalent  Stress  item  and  select  Evaluate  All
                                     Results, the solution in form of color fringe plot will appear
                                     as shown in the figure.

                                  6.4.1  Stress in Aircraft Structural Component
                                         A  structural  component  in  an  aircraft  wing  is  made
                              from  aluminum  material  that  has  the  Young’s  modulus  of
                                
                                          2
                                   10
                               710 N m  and Poisson’s ratio of 0.3.  The component is held
                              by internal screws at the two holes on the left portion of the figure.
                              The component is  subjected to an  offset loading  of 100  N at the
                              other  end.    Since  the  ANSYS  files  of  this  problem  can  be
                              downloaded from the book website, users can study the model in
