Plot shear force and bending moment diagrams for a cantilever beam acted on by a distributed load
portion A (0 < x < a) and solid portion B (a < x < a+b). Use a graphical interpretation of the differential and integral relationships among load, shear, and moment to construct these diagrams.
For the elastic portion A (Fig. 5.58) that has a rectangular cross-section area with a constant width c and a variable height h(x), find a function h(x) so that the maximum normal stress Omax(x) will be the same, irrespective of the distance x. Suppose h(a) = ho (Fig. 5.59).
