Consider a solid cylindrical shaft and a hollow cylindrical shaft. Both shafts are axisymmetric and elastic, and have the same cross-sectional area. The hollow shaft has an outside diameter of 150 mm and an inside diameter of 120 mm. When both the shafts are twisted by the same twisting moment, the ratio of maximum shear stress developed in the hollow shaft (𝜏ℎ) to maximum shear stress developed in the solid shaft (𝜏𝑠) will be______(rounded off to three decimal places).
Answer: 0.350 to 0.380
