This is a design problem, there are many acceptable designs.

Derive the axial shaft layout from figure 7-12.

Design for stress & Choose three critical locations (e.g shoulders, keyways, and grooves etc, depending on the shaft layout one designs). Design shaft diameter and verify the factor of safety for fatigue and yielding for each critical location.

Do force analysis to figure out the supporting forces at the bearings, and the shear force and bending moment diagrams.

Check and adjust for deflection.

Draw resulting shaft design in CAD.
