Bending Moment

In general, we can define the bending moment as the reaction induced when a certain amount of load or force is applied to an element which makes it bend.

Question

For the beam shown, the magnitude of the concentrated load is P = 21 kN, the magnitude of the couple is MB = 210 kN-m, and the beam
lengths are a = 4.3 m and b = 12.9 m.
(a) derive equations for the shear force V and the bending moment M for any location in the beam. Place the origin at point A.
(b) use the derived functions to plot the shear-force and bending-moment diagrams for the beam. Use your diagrams to determine the
magnitudes of the maximum shear force and the maximum bending moment.
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.
