Problem 6.5 A hollow aluminum shaft (G=27 GPa) is subjected to torques as shown. Determine (a) the maximum shear stress in the shaft (b) the angle of twist of the free end of the shaft. Solution: 0 A B C z (a) From B to C T BC 14 kN m := From A to B T AB 29 kN m T BC + := T AB 15 kN m = From 0 to A T 0A 25 kN m T AB + := T 0A 10 kN m = The maximum shearing stress occurs in the section with the largest torque r5 0 m m := J π 32 100 mm () 4 80 mm
