Shaft AB, with end A fixed on a block, is subjected to torques T=3 kNm and Tᵦ=1 kNm at locations C and B, respectively. The distance between A and C is a=0.1 m, and between C and B is b=0.15 m. The diameter of the shaft is d=40 mm. The shear modulus of the shaft material is G=100 GPa. Determine the twist angle at location B with respect to the fixed end A.
