* Your answer is incorrect. The composite shaft consists of two steel pipes that are connected at flange B and securely attached to rigid walls at A and C. Steel pipe (1) has an outside diameter of 8.625 in., a wall thickness of 2.6 in., and a length of L₁ = 17 ft. Steel pipe (2) has an outside diameter of 5.8125 in., a wall thickness of 1.14 in., and a length of L₂ = 24 ft. Both pipes have a shear modulus of 12900 ksi. If a concentrated torque of 30 kip-ft is applied to flange B, determine: (a) the maximum shear stress magnitudes T₁, T2 in pipes (1) and (2).
