The aluminium rod \( A B \) is bonded to the brass rod \( B D \) as shown in the figure. Knowing that portion \( C D \) of the brass rod is hollow and has an inner diameter of \( 46 \mathrm{~mm} \). The torque applied at point \( A \) is \( T_{A} \) \( =867 \mathrm{~N} \cdot \mathrm{m} \) and that at point \( \mathrm{B} \) is \( \mathrm{T}_{\mathrm{B}}=1,641 \mathrm{~N} \cdot \mathrm{m} \). Determine the largest shearing stress in this structure. (The answer is accurate to one decimal place, in the unit of MPa. Please write down only the value of the final result.)
