shear force and bending moment diagrams are graphical interpretation of shear and moment across the member. In this tutorial by Dr.Structure, We will learn how to draw these diagrams.

Using these diagrams we can quickly determine where maximum moment and shear are there on the member. These values are key factors in designing members so it is imperative to have basic idea of how these SFD and BMD are drawn.

Every design process requires certain parameters in order to design the capacity of members. These parameters serve as input in design process and at the end you get cross-sectional and material properties. This tutorial will not focus on design.

This video uses graphical approach to show how analysis of a beam is done and shear force and Bending moment diagram is drawn. Conventions are established at the start of the video. Concave up beam is taken as positive while concave down is taken as negative.
