Steel shaft AD (G = 80 GPa) is subjected to torsional loads at sections B and D, as shown in the figure. The diameters are: d1 = d2 = 40 mm., and d3 = 30 mm. (a) Determine the amount of torque T D φ C added at D that would make the rotation at C equal to zero, that is, let = 0. (b) For the loading as determined in Part (a), determine the maximum stress of shear in each of the three shaft segments. (answers: ?AB=-17.4 MPa ,?BC = 90 MPa ?CD=52 MPa, TC= -119 N.m, TD= 278 N.m)
