In Figure 4a, a beam is supported at A and C with a uniformly distributed load of 20 kN/m between A and B. Draw and label the shear force diagram (SFD) and bending moment diagram (BMD) for the beam shown in Figure Q3a. Label the values for shear force and bending moment at points A, B, C & at the beam mid-point M; the maximum bending moment and its distance from A; and clearly indicate the type of bending between AB and between BC.
