The aluminum rod AB (G=27 GPa) is bonded to the brass rod BD (G= 39 GPa). Knowing that portion CD of the brass rod is hollow and has an inner diameter of 54 mm, determine the angle of twist at A and B. 1100 N-m 36 mm 300 N-m 725 mm B 76 mm 650 mm D 550 mm Q (A)= (B) = The aluminum rod AB (G=27 GPa) is bonded to the brass rod BD (G= 39 GPa).
