Help with this Fluid mechanic problems please include the formula Determine the angle of twist of end $C$ with respect to end $A.$ The shaft has a

diameter of $40$ mm $.$

$0\mathrm{.}0533$ rad The A$-36$ steel pipe has a $6061-$T$6$ aluminum core. It is subjected to a tensile force of

$200$ kN $.$ Determine the average normal stress in the steel pipe due to this loading.

The pipe has an outer diameter of $80$ mm and an inner diameter of $60$ mm $.$
