Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Let a = 2.5 m, b = 6.3 m, P = 220 kN, wAC = 60 kN/m, and wCD = 130 kN/m. Label all significant points on each diagram and identify the maximum shear force and bending moment along with their respective locations. Additionally: (a) Determine V and M in the beam at a point located 1.9 m to the right of B. (b) Determine V and M in the beam at a point located 1.2 m to the left of D.

(b) Determine V and M in the beam at a point located 1.2 m to the left of D.
Note that answers may be positive or negative. Here, "maximum" refers to the largest magnitude value, but you should enter your shear force and bending moment with the correct sign, using the sign convention presented in Section 7.2 of the textbook. If the magnitudes of the largest positive and largest negative values are the same, enter a positive number.
