Problem 4. A 2 m long bar of circular cross-section is firmly fixed at its ends as shown in Fig.3. The bar is made of two cylinders of equal length and diameters of 20 cm and 10 cm. If a torque (T) is applied at the intersection of the two cylinders of shear moduli 100 MPa each, determine: (a) maximum shear stress in the bar. [3.0 points] (b) the twist angle at the point of application of the torque. [3.0 points] T = 40 kN Fixed edge Fixed edge Figure 3: Torsion of non-prismatic cylinder
