The torsional assembly consists of solid 3.0 in. diameter aluminum [G= 4,000 ksi] segments (1) and (3) and a central solid 3.4 in. diameter bronze [G= 6,500 ksi] segment (2). Segment lengths are L₁ - L3 = 38 in. and L₂ = 70 in. Concentrated torques of Tg = 2To and Tc-To are applied to the assembly at B and C, respectively. If the rotation angle at joint B must not exceed 2.2%, determine: (a) the maximum magnitude of To that may be applied to the assembly. (b) the maximum shear stress magnitude in aluminum segments (1) and (3). (c) the maximum shear stress magnitude in bronze segment (2). (1) B 2To L2 (2) C To L3 (3) D
