                                    Repeat  the  same  process  to  apply  boundary  condition  of
                                     zero displacement for X, Y and Z Components at the upper
                                     left end.
                                    Repeat  the  same  process  to  apply  boundary  condition  of
                                     zero displacement only for the Z Component at the lower
                                     right end.  Note that the Z displacement must be zero for all
                                     nodes of the 2D planar truss problems.
                                    Repeat the similar process to apply boundary condition of
                                     the two applied forces at the right hinge by first selecting
                                     the  Analysis  Settings,  select  the  Loads  tab  on  the  upper
                                     menu bar with Force option, and select Vertex icon.  Move
                                     the  cursor  to  the  right  hinge  and  click  at  it.    Select
                                     Components option on the right side of Define By in the
                                     Details of Force window.  Click Apply button, and input X
                                     Component as 500 and hit Enter, Y component as -2500
                                     and hit Enter.  Note that, mesh can be shown by clicking
                                     the Show Mesh icon on the upper menu bar.



















                                    This problem is a truss analysis, thus all the nodes must be
                                     the hinge type which are free to rotate.  Click Tools at the
                                     upper  tab  and  select  Options….  Select  Connections  and
                                     change the right side of Fixed Joints to No and click OK.
                                    The problem is now ready to solve for solution.  Right click
                                     the  Solution  item  and  under  Static  Structural  and  select
                                     the Solve tab.
