The problem consisting of determining the maximum torque that could be applied to

a rigid disk connecting a hollow aluminum sleeve and a solid steel shaft that was

introduced in the lecture video "Statically indeterminate torsional members $-$

example$-2"$ is shown below. The maximum torque that could be applied on the rigid

disk was determined to be dil $16$ Nm in the video.

Determine the the maximum shear stress occurring in the hollow aluminum sleeve

when $8116$ Nm is applied on the rigid disk and enter its magnitude in MPa $($mega

pascals$)$ correct to $3$ significant digits below. Note that the magnitude of shear stress

should be a positive number. You may use any of the values that were calculated for

this problem in the video to determine the maximum shear stress in the aluminum

sleeve.
