The cross sections of two hollow bars made of the same material are concentric circle as shown in the figure. It is given that r 3 > r 1 and r 4 > r 2 , and that the areas of the cross-sections are the same. J 1 and J 2 are the torsional rigidities of the bars on the left and right, respectively. The ratio J 2 /J 1 is

The cross sections of two hollow bars made of the same material are concentric circle as shown in the figure. It is given that r₃ > r₁ and r₄ > r₂, and that the areas of the cross-sections are the same. J₁ and J₂ are the torsional rigidities of the bars on the left and right, respectively. The ratio J₂/J₁ is
