2. A circular bar has a total length of L = 5m. As shown in Fig Q2, the cross-section of the bar changes at the length LAB = 4m. The cross-sections have a diameter of daß = 250mm and dBc = 125mm. According to Fig Q2, the bar is firmly supported at both ends. The applied torque T is T = 100kNm. For the shear modulus use G =75 GPa. (a) Calculate the maximum stress in the bar. (25 marks) (b) Calculate the angle of twist at location B, where T is applied. (5 marks) 100kNm Diameter 250mm Diameter 125mm tiom 4.Om Figure Q2: Circular bar with applied torque.
