A long circular shaft of length L with variable cross-section is fixed onto rigid walls as shown in
Figure 1.1. The polar moment of inertia of the L/3-long segment (J1) with a larger cross section
is three times larger than that of a 2L/3-long segment (J2) on the right. Assume the shear modulu
is constant and equal to G for the entire shaft and that strains are small and linear elastic.
