(a + b) (a-b)/2– w.a2/2. MB = w. (a2 - b2) /2– w.a2/2. MB = - w. b2/2. Bending moment at point B will be negative. As we can see here from above equation that bending moment at any section between A and B is following parabolic law and hence we can draw the bending moment diagram as displayed in above figure.
