 P: 70 If you've worked out the expression of the Shear Force, just integrate it with a minus sign outside to get the Bending Moment. $$M_{xz} = - \int F_{xy} dx$$ To double-check your answer, usually textbooks that describe beam theory will provide solutions to standard beam deflection problems. You can differentiate the expression for the deflection twice to get the expression for the bending moment. $$M_{xz} = EI \frac{d^2v}{dx^2}$$
