3.4-1 A stepped shaft ABC consisting of two solid circular segments is subjected to torques 7, and 72 acting in oppo- site directions, as shown in the figure. The larger segment of the shaft has a diameter of d =58 mm and length 760 mm; the smaller segment has a diameter of d45 mm and length of L = 510 mm. The material is steel with shear modulus G-76 GPa, and the torques ards 7, 2300 Nm and 7 900 N-m. (a) Calculate the maximum shear stress Tax in the shaft and the angle of twist o (in degrees) at end C (b) If the maximum shear stress in BC must be the same as that in AB, what is the required diameter of seg- ment BC? What is the resulting twist at end C? A Lo Li
