4 The design of a beam requires a detailed  knowledge of the variation of internal  Shear Force V  and  Bending Moment M   acting at each point along the axis of the  beam Then using Theory of Mechanics of  Materials and appropriate engineering  design codes to determine the beam’s  required cross sectional area

5 Variations in V and M are  expressed as functions of the  position  x  along the beam’s axis Plotting these variations of V and  M of  x  are termed the  Shear  Force and Bending Moment  Diagrams
