Start with the shear diagram. To use a segment of the left end of the beam to develop the expression for the shear, the vertical reaction at A must be known. Calculate the vertical reaction at A. Let a positive force act up.   Write an expression for the internal shear for an arbitrary point between A and B.   Write an expression for the internal shear for an arbitrary point between B and C.   Draw the shear diagram for the beam.   Write an expression for the bending moment at an arbitrary point between A and B. Use the standard sign convention for the internal moment for a beam.   Write an expression for the bending moment at an arbitrary point between B and C.   Draw the moment diagram for the beam.
