8.8 (A/B). Opposing axial torques are applied at the ends of a straight bar ABCD. Each of the parts AB, BC and CD is 500 mm long and has a hollow circular cross-section, the inside and outside diameters being, respectively, AB 25 mm and 60 mm, BC 25 mm and 70mm, CD 40 mm and 70 mm. The modulus of rigidity of the material is 80 GN/m³ throughout. Calculate: (a) the maximum torque which can be applied if the maximum shear stress is not to exceed 75 MN/m²; (b) the maximum torque if the twist of D relative to 4 is not to exceed 2. [E.I.E.] [3.085 kN m, 3.25 kNm.]
