                 Consequently,  in the  flat oblique  bending  full  deflection
           f
          is perpendicular to the neutral axis.
                 The equality (1.13) shows that the larger the ratio  J J ,
                                                                    z   y
          the  greater  the  difference  between  the  angles   and   .

          Therefore, for narrow and tall sections, in which the ratio of the
          main moments of inertia is large enough, the plane has a slight
          deviation  to  the  external  plane  of  greatest  stiffness  causes  a
          significant  deviation  plane  bending  beam,  which  should  be
          considered when designing.

          1.3 Eccentrical tension - compression

                 Eccentrical  tension  -  compression  is  the  type  of
          deformation,  when  in  the  cross  section  of  the  rod  longitudinal
          force and bending moment simultaneously apply.
