A cross section of an engineering structure made of steel is shown in the Figure. For an applied torque of \( \mathrm{T}=175 \mathrm{~N} . \mathrm{m} \), (a) determine how much torque is carried by each of the two cross-sectional components and (b) the angle of twist per unit length. The shear modulus \( \mathrm{G}=200 \mathrm{GPa} \). (Neglect the stress concentrations).
