Find the value of the maximum transverse shear stress for the beams of the following figures:

Figure 1 shows the loads and general dimensions of a freight car. The horizontal load is due to centrifugal effects in passing around a curve. The loading shown is for one axle. Make a force diagram showing the equilibrium of a unit consisting of one axle and two wheels. The centrifugal force is assumed to be applied to the axle at the inner bearing only, and to be resisted by the Hange of the outer wheel only. Also, draw and dimension the bending moment diagram for the axle. Wheels are press-fitted to the axle.
