The thickness of a uniform hollow circular shaft is equal to the difference between
the outer radius and the inner radius. The ratio of the inner diameter to outer
diameter of the shaft is 0.5 . For the shaft reacting to an applied torque, the ratio of
the maximum shear stress
to the maximum shear stress
thin wall - obtained using
the thin-wall approximation is . (round off to one decimal place)
