PROBLEM2:This is a finite element method problem,and see the figure2
in the  http://home.attbi.com/~josephsieh                             
             Analyze  the beam use the finite element method
          (a)use the simplest possible mesh
          (b)use a mesh with 6 beam elements
          (c)find the rotation  at point A
PS:I want to get the answer within 2 days
