The round stepped shaft (diameters d and D) shown below is a design for an exoplanet rover wheel axle. Assuming the wheel is stuck, a torque from the motor is transmitted to the axle but it is not rotating. The reaction of the weight of the rover on the ground and the torque the wheel applies to the ground are represented by the force F acting in the center of the wheel hub (not shown) at point C. There is a sharp fillet at B with radius r shown below. Bearings are shown at point A and next to point B. You may assume the bearing at B resists the bending moment caused by the force F and acts like a fixed reaction.
