$($xi$)$ If $T_B$ remains counterclockwise as shown, but $T_C$ was instead applied clockwise,

which of the following statements is true?

$($q$)$ The maximum shear stress would be in segment BC and would be smaller than

before.

$($r$)$ The maximum shear stress would remain in segment AB and would be smaller than

before.

$($s$)$ The maximum shear stress would be in segment BC and would be larger than before

because of the opposing torques applied.

$($t$)$ The maximum shear stress would remain in segment AB and would be larger than

before because of the opposing torques applied.
