Consider the cantilever beams illustrated below and plot qualitative diagrams outlining the variations of the axial force, shear force and bending moment along the beam length. In these diagrams, specify the order of the polynomial describing the internal actions, for example, stating whether the curves are linear, parabolic or cubic.
