For accuracy better than 5%, the following assumptions must hold:

1.  Beam is homogeneous

2.  Curvature in plane of bending is > 10 times beam thickness, i. e., the beam is straight

3.  Beam cross-section is uniform

4.  Beam has at least one longitudinal plane of symmetry

5.  All loads and reactions are perpendicular to the beam axis

6.  Length and width > 5* thickness

7.  The maximum stress does not exceed the yield strength

8.  The deflection <  thickness
