In the case of a beam, it can be calculated as the algebraic sum of the moments on the section of all the forces acting on each side of the section, where a falling moment will make the beam concave (positive) upwards in that section, and vice versa for a hoarding moment. But to draw a shear force and bending moment diagram, we need to know how these values change across the structure. Therefore, we can say that we have one cantilever beam here and we will have to find the method to draw shear force and bending moment diagram. Also, draw shear and moment diagrams, specifying values at all change of loading In the last section we worked out how to evaluate the internal shear force and bending moment at a discrete location using imaginary cuts.
