Figure Q1 shows a shaft AB (modulus of rigidity G = 73 GPa) with a total length of 1270 mm that is fixed at both ends. Section AC is solid with a diameter of do = 80 mm, while CB is a hollow section with an internal diameter of di = 60 mm. An external torque T0 = 10 kN.m is applied at point D. B) What is the maximum angle of twist, max and where does it occur?
