maximum shear stress developed

Question

Two solid circular shafts of R₁ and R₂ are subjected to same torque. The maximum shear stress developed in the two shafts are $\tau _{1}$ and $\tau _{}$. If $\frac{R_{1}}{R_{2}}$ = 2, then $\frac{\tau _{1}}{\tau _{2}}$ is _________

Answer 1

Given radius of shaft 1 is twice that of radius of shaft 2,
