  A new general equation to explain bending of arbitrary rods (from arbitrary
materials, cross sections, densities, strengthnesses, bending angles, etc) was
proposed. This equation can solve several problems found in classical
equations, which have many limitations such as only applies for small bending
angles or must be solved using very complex schemes. Experiments were also
conducted to confirm the theoretical predictions. The equation might be used to
explain bending of palm fronds in a very simple way. The proposed equation may
be used to obtain solution of several problems which are usually obtain with
iteration procedures.
