Question

I just need A in detail

9.3 a) For the beam shown in Fig. 9.3, draw the shear force and bending moment diagrams. Use the area method that relies on the relationships between loading and shear force and between shear force and bending moment. Indicate the slope of the shear force diagram at locations A, B, C, and D using the load information in Fig. 9.3. Indicate the slope of the bending moment diagram at the same four locations using information from the shear force diagram. 4 kN/m IN A B C D + 2m + 2m + 2m Figure 9.3
