PLEASE ANSWER i, ii, iii In the stepped shaft shown in Fig Q2, which has a full quarter-circular fillet, the allowable shearing stress is 80 MPa. Given that
D=30mm, Determine the largest allowable torque that can be applied to the shaft if: (i)
d=26mm. [9 Marks] (ii)
d=24mm.[9 Marks] (iii) What is the effect of decrease in the diameter of the smaller shaft on the structural integrity of the stepped shaft? Fig. Q2: Full quarter-circular fillet extends to edge of larger shaft.
