5.5-8 A freight-car axle AB is loaded approximately as shown in the figure, with
the forces P representing the carloads (transmitted to the axle through the axle
boxes) and the forces R representing the rail loads (transmitted to the axle through
the wheels). The diameter of the axle is d = 82 mm, the distance between centers
of the rails is L, and the distance between the forces P and R is b = 220 mm.

First section: Make an arbitrary cut between points
A and B. Take the distance of the cut to be x along the beam
from point A. Draw the free-body diagram for the left section
and find functions for the internal shear force, V(x), and bending
moment, M(x), in the section of the beam between A and B.
