1) The document discusses shear force diagrams and bending moment diagrams for loaded beams. It provides equations that govern loaded beams and defines clockwise and anticlockwise moments. 2) An example beam with different loads is used to calculate support reactions, draw the shear force diagram, and bending moment diagram. The shear force diagram shows vertical forces plotted against distance along the beam. 3) The bending moment diagram is created by calculating the area under the shear force diagram section by section, and plots bending moment against distance along the beam. This shows how bending moment changes along the beam.
