The aluminium rod AB is bonded to the brass rod BD as shown in the figure. Knowing that portion CD of the brass rod is hollow and has an inner diameter of 41 mm. The torque applied at point A is TA = 897 N-m and that at point B is TB = 1,609 N-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.) TA 36 mm TB 400 mm 60 mm 375 mm D 250 mm
