Consider a Boeing 787 and assume the fuselage cross-section to be circular with a diameter d=5.9m, a skin thickness t=2mm, and isotropic material properties of E=60GPa and ν=0.28.

The vertical tail plane applies a torsional moment of the rear fuselage, inducing a shear flow in the rear fuselage skin.

Calculate the shear stress τ in the rear fuselage skin for the assumed fuselage diameter and thickness if a torsional moment of MT=1.8⋅10^6N⋅m is applied.
Hint:Apply q=MT/2A.
