It is made of solid circular cross-section bars, whose geometry and loading condition are given in Figure 2. The system formed is made of steel material and the torsional moments is under the influence. The diameter of the AB part of the rod is 100 mm; The diameter of the BC part is 60 mm. the shear modulus of steel is G = 80000 MPa.
(a) Draw the torsional moment diagram of the rod.
(b) Calculate the maximum shear stress that will develop in the system.
(c) Calculate the relative rotational value of point C with respect to point A.
