Section: Solid Mechanics | Marks: 2
A circular shaft is rigidly connected to a wall at one end. The shaft has a solid portion and a hollow portion as shown in the figure. The length of each portion is 𝐿 and the shear modulus of the material is 𝐺. The polar moment of inertia of the hollow portion is 𝐽 and that of the solid portion is 50𝐽. A torque 𝑇 is applied at the right most end as shown. The rotation of the section PQ is
